/*
* ext2spice.c --
*
* Program to flatten hierarchical .ext files and produce
* a .spice file, suitable for use as input to simulators
* such as spice and hspice.
*
* Flattens the tree rooted at file.ext, reading in additional .ext
* files as specified by "use" lines in file.ext. The output is left
* in file.spice, unless '-o esSpiceFile' is specified, in which case the
* output is left in 'esSpiceFile'.

#include <ctype.h>
Important update: Reworked the extraction method to properly isolate the terminal areas of a device (e.g., source and drain) and calculate their area and perimeter individually for the device (in addition to the traditional method of calculating area and perimeter of each resistance class for the entire node). Also: Reworked the SPICE syntax output to generate SI values in the range 1-1000 with the appropriate suffix (e.g., "20u") instead of defaulting to "u" for lengths and "p" for areas. This prevents it from producing weird units like "150000u" when a process definition already includes a scalefactor. Reworked the "extresist" code to use the device terminal area and perimeter. This fixes an error in which "extresist" would lose these values and "ext2spice" with option "extresist on" would generate a new netlist output with zero terminal areas and perimeters.

Changed the behavior of capacitance value output in ext2spice and ext2sim to make use of the new esSIvalue() routine, so that it no longer depends on a preformatted string. Corrected an issue where the esSIvalue() routine would output "a" for "atto" which is not supported by ngspice.

Implemented a command option "ext2spice short voltage|resistor|none" that implements a method for handling ports in a subcircuit that have different port names and indexes but are shorted together. "none" is the default and backwards-compatible behavior that merges ports together, which will often cause one of the ports to be optimized out of the netlist. "resistor" will separate the port names with a 0-ohm ideal resistor. "voltage" will separate the port names with a 0-volt voltage source. This should work well for simulation and potentially for LVS, although its impact on LVS has not been fully investigated.

Corrected an issue with the limited bitfield dedicated to port numbers; this limited ports to 16384, which seemed reasonable at the time. However, the sky130_sram_macro layouts connect power and ground in a way that when coupled with "extract unique" can generate tens of thousands of ports and overrun the bit field, showing that automation can do the unexpected. The solution was to split out the port number from the label record as its own 32-bit value.

Restored compiling of the non-Tcl/Tk version of magic. This has traditionally been kept for backwards compatibility. However, the operation of "ext2spice" and "ext2sim" as separate programs has become extremely difficult to maintain, and so it has been dropped in favor of folding both into the program as commands, as was done a long time ago in the Tcl/Tk version.

Tracked down two more memory leaks coming from ext2spice, due to client data generated by ext2spice and attached to a node's nodeClient record; there is an initNodeClient() routine but no corresponding freeNodeClient() routine. Eventually had to add a callback function passed to EFDone() and EFFlatDone() to clean up these entries. After doing that, valgrind reports clean for all memory allocated within ext2spice (there are other things that are not freed but not related to a specific command, so do not need to be treated as leaks).

Separated drain and source records for the esFetInfo array, to support asymmetric FETs and other devices like bipolars that have three distinct terminals. This does not go as far as it should to make the array independent of the number of declared terminals of the device. However, it suffices to make, e.g., parameter "a2=area" work for a bipolar device, and to generate the right drain and source areas and perimeters for asymmetric (e.g., extended-drain) devices.

Made a change to the way ext2sim determines if a FET type is an n or p device; this was previously dependent only on the first character of the extracted device model name. Since the tech file has control over what the device layer names are but not the extracted model names, the device layer type name is used as a backup way to determine if the type is n or p, if that cannot be determined from the extracted model name.

"blackbox [on|off] output abstract views as black-box entries",
Initial commit at Tue Apr 25 08:41:48 EDT 2017 by tim on stravinsky
2017-04-25 14:41:48 +02:00
"renumber [on|off] on = number instances X1, X2, etc.\n"
" off = keep instance ID names",
"global [on|off] on = merge unconnected global nets by name",
Two improvements: (1) Command extension "ext2spice lvs" sets up all the settings normally used for LVS (hierarchy on, cthresh infinite, subcircuit top auto, etc.). (2) Extract and extract unique ignore cells marked as abstract views (property LEFview is set) when checking for unconnected nets with the same name label.

Implemented a command option "ext2spice short voltage|resistor|none" that implements a method for handling ports in a subcircuit that have different port names and indexes but are shorted together. "none" is the default and backwards-compatible behavior that merges ports together, which will often cause one of the ports to be optimized out of the netlist. "resistor" will separate the port names with a 0-ohm ideal resistor. "voltage" will separate the port names with a 0-volt voltage source. This should work well for simulation and potentially for LVS, although its impact on LVS has not been fully investigated.

Restored compiling of the non-Tcl/Tk version of magic. This has traditionally been kept for backwards compatibility. However, the operation of "ext2spice" and "ext2sim" as separate programs has become extremely difficult to maintain, and so it has been dropped in favor of folding both into the program as commands, as was done a long time ago in the Tcl/Tk version.

Implemented a command option "ext2spice short voltage|resistor|none" that implements a method for handling ports in a subcircuit that have different port names and indexes but are shorted together. "none" is the default and backwards-compatible behavior that merges ports together, which will often cause one of the ports to be optimized out of the netlist. "resistor" will separate the port names with a 0-ohm ideal resistor. "voltage" will separate the port names with a 0-volt voltage source. This should work well for simulation and potentially for LVS, although its impact on LVS has not been fully investigated.

Corrects "ext2spice hierarchy off" when subcircuits with ports are present. Note, however, this fix breaks the use of "ext2spice subcircuit descend off" because subcircuits are always descended into. It's not clear that "subcircuit descend off" worked at all before, anyway. That still needs fixing.

Made a change to the way ext2sim determines if a FET type is an n or p device; this was previously dependent only on the first character of the extracted device model name. Since the tech file has control over what the device layer names are but not the extracted model names, the device layer type name is used as a backup way to determine if the type is n or p, if that cannot be determined from the extracted model name.

Important update: Reworked the extraction method to properly isolate the terminal areas of a device (e.g., source and drain) and calculate their area and perimeter individually for the device (in addition to the traditional method of calculating area and perimeter of each resistance class for the entire node). Also: Reworked the SPICE syntax output to generate SI values in the range 1-1000 with the appropriate suffix (e.g., "20u") instead of defaulting to "u" for lengths and "p" for areas. This prevents it from producing weird units like "150000u" when a process definition already includes a scalefactor. Reworked the "extresist" code to use the device terminal area and perimeter. This fixes an error in which "extresist" would lose these values and "ext2spice" with option "extresist on" would generate a new netlist output with zero terminal areas and perimeters.

Implemented a command option "ext2spice short voltage|resistor|none" that implements a method for handling ports in a subcircuit that have different port names and indexes but are shorted together. "none" is the default and backwards-compatible behavior that merges ports together, which will often cause one of the ports to be optimized out of the netlist. "resistor" will separate the port names with a 0-ohm ideal resistor. "voltage" will separate the port names with a 0-volt voltage source. This should work well for simulation and potentially for LVS, although its impact on LVS has not been fully investigated.

(1) Added a check for unclosed boundaries when reading GDS. This is diagnostic only and does not change the read-in behavior. (2) ext2spice: Corrected an error that had been introduced into version 8.3.171 that accidentally marks all devices as visited which causes all source/drain areas and perimeters to be output as zero. (3) extract: Sweeping changes to handling of fringe capacitance. Removed the (recently added) "fringeshieldhalo" parameter from the tech file. Reworked the fringe capacitance models based on results from the "capiche" project (github/RTimothyEdwards/capiche). Fringe shielding is now done by clipping fringe at the boundary of a shielding shape, rather than trying to calculate the amount of shielding (as the "capiche" project proved this to be equivalent). Values for partial fringing are modeled by atan(x), which like the sidewall (1/x) curve, extends to infinity and values are limited by the halo but do not otherwise depend on the halo. Because of this, the halo can be made variable and controlled by the user for deciding on the tradeoff between accuracy and run time. A new command option "extract halo" was added to allow this control over the halo distance.

Corrected an issue with the limited bitfield dedicated to port numbers; this limited ports to 16384, which seemed reasonable at the time. However, the sky130_sram_macro layouts connect power and ground in a way that when coupled with "extract unique" can generate tens of thousands of ports and overrun the bit field, showing that automation can do the unexpected. The solution was to split out the port number from the label record as its own 32-bit value.

Corrected a previous implementation that was supposed to not print warning messages about ports being electrically connected when those ports have names that match under rules of case-insensitivity, and the .ext file is being read for the purpose of generating a SPICE netlist, which is case-insensitive.

Important update: Reworked the extraction method to properly isolate the terminal areas of a device (e.g., source and drain) and calculate their area and perimeter individually for the device (in addition to the traditional method of calculating area and perimeter of each resistance class for the entire node). Also: Reworked the SPICE syntax output to generate SI values in the range 1-1000 with the appropriate suffix (e.g., "20u") instead of defaulting to "u" for lengths and "p" for areas. This prevents it from producing weird units like "150000u" when a process definition already includes a scalefactor. Reworked the "extresist" code to use the device terminal area and perimeter. This fixes an error in which "extresist" would lose these values and "ext2spice" with option "extresist on" would generate a new netlist output with zero terminal areas and perimeters.

Implemented a command option "ext2spice short voltage|resistor|none" that implements a method for handling ports in a subcircuit that have different port names and indexes but are shorted together. "none" is the default and backwards-compatible behavior that merges ports together, which will often cause one of the ports to be optimized out of the netlist. "resistor" will separate the port names with a 0-ohm ideal resistor. "voltage" will separate the port names with a 0-volt voltage source. This should work well for simulation and potentially for LVS, although its impact on LVS has not been fully investigated.

(1) Added a check for unclosed boundaries when reading GDS. This is diagnostic only and does not change the read-in behavior. (2) ext2spice: Corrected an error that had been introduced into version 8.3.171 that accidentally marks all devices as visited which causes all source/drain areas and perimeters to be output as zero. (3) extract: Sweeping changes to handling of fringe capacitance. Removed the (recently added) "fringeshieldhalo" parameter from the tech file. Reworked the fringe capacitance models based on results from the "capiche" project (github/RTimothyEdwards/capiche). Fringe shielding is now done by clipping fringe at the boundary of a shielding shape, rather than trying to calculate the amount of shielding (as the "capiche" project proved this to be equivalent). Values for partial fringing are modeled by atan(x), which like the sidewall (1/x) curve, extends to infinity and values are limited by the halo but do not otherwise depend on the halo. Because of this, the halo can be made variable and controlled by the user for deciding on the tradeoff between accuracy and run time. A new command option "extract halo" was added to allow this control over the halo distance.

Removed code from ext2spice that is no longer functional. Implemented a separate check for ports when writing a subcircuit that cross-checks against the port list in the flattened extraction. This allows ports that were optimized out during flattening of the hierarchy to be removed from the cell's port list, which cuts down on disconnected nodes in the output port list.

Again revisited the problem of duplicate nodes. This time, I think I understand the problem, which is that nodes are ordered according to precedence of EFHNBest() within a circuit, but there is no concept of ordering between circuits. So ports end up listing nodes in arbitrary order, and the only way to resolve the order is to use EFHNBest() as is done within a subcircuit. Appears to work for different edge cases tested.

Corrected hierarchical SPICE extraction to reset the subcircuit name-to-number mapping used for the HSPICE format between subcircuits. Otherwise, subcircuits with the same instance ID remain in the table and may cause nodes to be output with a name that collides with other names in the same subcircuit. This only affects output in HSPICE format.

Implemented a command option "ext2spice short voltage|resistor|none" that implements a method for handling ports in a subcircuit that have different port names and indexes but are shorted together. "none" is the default and backwards-compatible behavior that merges ports together, which will often cause one of the ports to be optimized out of the netlist. "resistor" will separate the port names with a 0-ohm ideal resistor. "voltage" will separate the port names with a 0-volt voltage source. This should work well for simulation and potentially for LVS, although its impact on LVS has not been fully investigated.

Resolved some issues with working with ext2spice using abstract views. Because the abstract view does not necessarily represent actual connectivity, rely on the port indexes in the .ext file to determine the number of ports and port order. Do not use SpiceNodeName() to look up the node name, or unique ports that are deemed shorted will go missing. Also: Modified the read-in of .ext files so that use names may contain backslashes. Only backslashes that end a line will be handled differently.

Corrected two annoying errors: (1) SPICE netlist output subcircuits could have multiple ports of the same name. This problem had been worked over before, but there was an indpendent mechanism producing the same result for a completely different reason, caused by subcells being much larger than the cookie-cutter extraction method's extraction regions. Solved by tracking port names in a hash table and preventing re-use. (2) ext2spice was producing "no such node" errors; like (1) this had been previously worked on, and like (1) this mechanism was independent. Problem came from not passing -1 to extHierSubstrate for the non-arrayed dimension of a 1-dimensional array. Also: Removed the word "fatal" from extraction error reporting, as nearly all extraction errors are entirely benign. This should clear up confusion among alarmed end-users.

Made some changes to the way that ext2spice generates subcircuit ports, to avoid creating ports for node names that are redundant. It would probably be better to avoid creating the redundant node names in the first place; however, I am less certain why these are generated. The incorrect additional ports all have hierarchical names in the cell, which is a sign that they are incorrect, as the cell itself should not have any parents. The level of certainty about this fix is definitely not 100%, but it was tested on a hierarchical analog design, and setting levels of parasitic caps caused new nodes to appear in subcircuits and in no cases did information appear to be lost.

Added a 2nd use of the "device" property, which has long been needed, which instead of defining a device or subcircuit that exists inside the cell, instead redefines the cell itself as a device or subcircuit model that exists in the PDK. This is used where a specific layout subcell has its own associated device definition in the PDK. Instead of the "device" property value being the line that gets generated for a device in the subcells .ext file, the property value should be the word "primitive" optionally followed by any parameters that need to be passed to the subcircuit call.

Corrected ext2spice for the case where a port has been given more than one name, because in that case one of the port records ends up with a null pointer to a node, and causes a crash condition. This can happen inadvertently, as when a connected node is not specifically designated a port, but is forced to be a port because of the connection.

Removed code from ext2spice that is no longer functional. Implemented a separate check for ports when writing a subcircuit that cross-checks against the port list in the flattened extraction. This allows ports that were optimized out during flattening of the hierarchy to be removed from the cell's port list, which cuts down on disconnected nodes in the output port list.

(1) Modified the method used for the previous commit, as it was found to make ext2spice runtimes very long for large layouts. The new method is equivalent but doesn't incur the overhead. Also: Changed a flag check which was causing the substrate node to be output as a port for certain layouts where the substrate node connects to no devices, and so should be optimized out.

Cleaned up a bit of confusing diagnostic output when reading GDS. If cells are instanced before being defined, causing the GDS parser to rewind the cell from the top, then the "already defined" error messages will be suppressed, since it is to be expected that cells will be seen twice (and ignored the 2nd time). When rewinding, an output message is issued so that it is clear that the file contains instances that are used before they are defined, and recommends the "gds ordering on" setting. Also: Fixed the "gds ordering" command code so that the command with no third argument returns the state of the "gds ordering" setting instead of generating a parser error.

Corrected an issue that produces potentially incorrect output from ext2spice due to "equiv" statements in the .ext file. The algorithm was not properly keeping the port as the preferred name of the node, resulting in the non-preferred name being used instead of the port name in the output. This would happen only if there was a label on a net that had a different name than the port name. The error became much more prevalent after changing the extract behavior to make "extract do aliases" default. Also fixed a somewhat related minor error in which magic would print an error message about ports being shorted together on the same kind of net where both a port and a (different) label were attached to the net. Since the non-port label is not a preferred name, then there should be no warning message. The warning is only intended for cases where two (or more) ports are truly shorted together.

// pname = nodeSpiceName(snode->efnode_name->efnn_hier, NULL);

Corrected two annoying errors: (1) SPICE netlist output subcircuits could have multiple ports of the same name. This problem had been worked over before, but there was an indpendent mechanism producing the same result for a completely different reason, caused by subcells being much larger than the cookie-cutter extraction method's extraction regions. Solved by tracking port names in a hash table and preventing re-use. (2) ext2spice was producing "no such node" errors; like (1) this had been previously worked on, and like (1) this mechanism was independent. Problem came from not passing -1 to extHierSubstrate for the non-arrayed dimension of a 1-dimensional array. Also: Removed the word "fatal" from extraction error reporting, as nearly all extraction errors are entirely benign. This should clear up confusion among alarmed end-users.
2020-11-24 21:30:49 +01:00
There being a specific situation where the enumeration of ports used by "topVisit" and "subcktVisit" in ext2spice.c, probably caused by having different names on the same port number, the subcktVisit() routine was modified to use exactly the same enumeration as topVisit() so that they are guaranteed to have the same result.

Implemented simple drain and source length calculations as device parameters l1 and l2. Provides a way to pass the source or drain length as a parameter for, for example, an extended FET drain implemented as a resistor abutting the FET gate. Could potentially be used as a way to determine source/drain area and perimeter without resorting to measurements of a shared node.

Important update: Reworked the extraction method to properly isolate the terminal areas of a device (e.g., source and drain) and calculate their area and perimeter individually for the device (in addition to the traditional method of calculating area and perimeter of each resistance class for the entire node). Also: Reworked the SPICE syntax output to generate SI values in the range 1-1000 with the appropriate suffix (e.g., "20u") instead of defaulting to "u" for lengths and "p" for areas. This prevents it from producing weird units like "150000u" when a process definition already includes a scalefactor. Reworked the "extresist" code to use the device terminal area and perimeter. This fixes an error in which "extresist" would lose these values and "ext2spice" with option "extresist on" would generate a new netlist output with zero terminal areas and perimeters.

Extended the device parameters to allow a terminal width that is different from the device (i.e., gate) width, for devices that do not define a MOS-like gate spanning the width of the device. This is restricted to the assumption that the terminal is rectangular and therefore a simple width and length can be derived from the area and perimeter. Also, length is defined as the smaller dimension and width as the larger dimension. For additional restrictions, see the updated documentation. This was added to allow correct width and length extraction of a bipolar emitter window, but may be more generally useful.

Important update: Reworked the extraction method to properly isolate the terminal areas of a device (e.g., source and drain) and calculate their area and perimeter individually for the device (in addition to the traditional method of calculating area and perimeter of each resistance class for the entire node). Also: Reworked the SPICE syntax output to generate SI values in the range 1-1000 with the appropriate suffix (e.g., "20u") instead of defaulting to "u" for lengths and "p" for areas. This prevents it from producing weird units like "150000u" when a process definition already includes a scalefactor. Reworked the "extresist" code to use the device terminal area and perimeter. This fixes an error in which "extresist" would lose these values and "ext2spice" with option "extresist on" would generate a new netlist output with zero terminal areas and perimeters.

Fixed a long-standing error in which "ext2spice merge" fails when used with "ext2spice hierarchy on" because the device index is not reset between calls to output cells in the hierarchy, leading to a mismatch of the index for all cells after the first one output.

Implemented a command option "ext2spice short voltage|resistor|none" that implements a method for handling ports in a subcircuit that have different port names and indexes but are shorted together. "none" is the default and backwards-compatible behavior that merges ports together, which will often cause one of the ports to be optimized out of the netlist. "resistor" will separate the port names with a 0-ohm ideal resistor. "voltage" will separate the port names with a 0-volt voltage source. This should work well for simulation and potentially for LVS, although its impact on LVS has not been fully investigated.

Implemented a command option "ext2spice short voltage|resistor|none" that implements a method for handling ports in a subcircuit that have different port names and indexes but are shorted together. "none" is the default and backwards-compatible behavior that merges ports together, which will often cause one of the ports to be optimized out of the netlist. "resistor" will separate the port names with a 0-ohm ideal resistor. "voltage" will separate the port names with a 0-volt voltage source. This should work well for simulation and potentially for LVS, although its impact on LVS has not been fully investigated.

Important update: Reworked the extraction method to properly isolate the terminal areas of a device (e.g., source and drain) and calculate their area and perimeter individually for the device (in addition to the traditional method of calculating area and perimeter of each resistance class for the entire node). Also: Reworked the SPICE syntax output to generate SI values in the range 1-1000 with the appropriate suffix (e.g., "20u") instead of defaulting to "u" for lengths and "p" for areas. This prevents it from producing weird units like "150000u" when a process definition already includes a scalefactor. Reworked the "extresist" code to use the device terminal area and perimeter. This fixes an error in which "extresist" would lose these values and "ext2spice" with option "extresist on" would generate a new netlist output with zero terminal areas and perimeters.

Made some changes to the way that ext2spice generates subcircuit ports, to avoid creating ports for node names that are redundant. It would probably be better to avoid creating the redundant node names in the first place; however, I am less certain why these are generated. The incorrect additional ports all have hierarchical names in the cell, which is a sign that they are incorrect, as the cell itself should not have any parents. The level of certainty about this fix is definitely not 100%, but it was tested on a hierarchical analog design, and setting levels of parasitic caps caused new nodes to appear in subcircuits and in no cases did information appear to be lost.

Possible fix to problem with substrate node being unitialized when called after "merge conservative" is selected in ext2spice.
2017-10-20 22:07:52 +02:00
Got to the bottom of why area and perimeter values are no longer output for transistors. The problem came from a change made to fix an issue with capacitors marked as floating nodes because some nodes are not output as source or drain. But those nodes are output before the parameters, so when generating parameter output, all nodes appear to have already been output. Solution: Specify an additional bit in the "visited" mask for the node having been output that is separate from the mask for resist classes used by the code that writes parameter values, and use that bit as a test for whether the node is connected to some device (not necessarily a FET source or drain).

/* Create node client if it doesn't exist */
Restored compiling of the non-Tcl/Tk version of magic. This has traditionally been kept for backwards compatibility. However, the operation of "ext2spice" and "ext2sim" as separate programs has become extremely difficult to maintain, and so it has been dropped in favor of folding both into the program as commands, as was done a long time ago in the Tcl/Tk version.

Adjusted the bounds where each SI suffix is used to keep output in the range of 0.1 to 100, although the boundary is very subjective. Made a correction to the extresist code to scan through all device records for a tile type. However, (1) there are cases being missed, and (2) this should not be necessary since all device types should be able to be known exactly from the contents of the .sim file. Needs more work.

Important update: Reworked the extraction method to properly isolate the terminal areas of a device (e.g., source and drain) and calculate their area and perimeter individually for the device (in addition to the traditional method of calculating area and perimeter of each resistance class for the entire node). Also: Reworked the SPICE syntax output to generate SI values in the range 1-1000 with the appropriate suffix (e.g., "20u") instead of defaulting to "u" for lengths and "p" for areas. This prevents it from producing weird units like "150000u" when a process definition already includes a scalefactor. Reworked the "extresist" code to use the device terminal area and perimeter. This fixes an error in which "extresist" would lose these values and "ext2spice" with option "extresist on" would generate a new netlist output with zero terminal areas and perimeters.

Applied patch from Donn that converts strcpy() calls in ext2spice to "safer" strncpy() calls to prevent string buffer overflow. Also: Reimplemented the loop in the GDS write routine that counts ports and then outputs them in order. It was possible to hang magic for a long time by giving a port a very, very large index number. The new implementation uses qsort() to sort the ports by index, which is obviously much more efficient for the worst case (and efficient enough for all normal cases).

Modified the LEF VIAGEN reading such that it can accomodate a different order of layers than specified in the LEF/DEF spec. It is not clear whether this is common practice, or a bug in the tool that produced the DEF file that prompted this change. NOTE: The "grow" function applied in this case should be replaced by the actual GDS input rule sequence, that includes the grow and shrink merge. Otherwise, vias read from DEF files do not match the layout from those read from GDS, even though the mask layers represented by the layouts are the same.

Important update: Reworked the extraction method to properly isolate the terminal areas of a device (e.g., source and drain) and calculate their area and perimeter individually for the device (in addition to the traditional method of calculating area and perimeter of each resistance class for the entire node). Also: Reworked the SPICE syntax output to generate SI values in the range 1-1000 with the appropriate suffix (e.g., "20u") instead of defaulting to "u" for lengths and "p" for areas. This prevents it from producing weird units like "150000u" when a process definition already includes a scalefactor. Reworked the "extresist" code to use the device terminal area and perimeter. This fixes an error in which "extresist" would lose these values and "ext2spice" with option "extresist on" would generate a new netlist output with zero terminal areas and perimeters.

Applied patch from Donn that converts strcpy() calls in ext2spice to "safer" strncpy() calls to prevent string buffer overflow. Also: Reimplemented the loop in the GDS write routine that counts ports and then outputs them in order. It was possible to hang magic for a long time by giving a port a very, very large index number. The new implementation uses qsort() to sort the ports by index, which is obviously much more efficient for the worst case (and efficient enough for all normal cases).

Made some changes to the way that ext2spice generates subcircuit ports, to avoid creating ports for node names that are redundant. It would probably be better to avoid creating the redundant node names in the first place; however, I am less certain why these are generated. The incorrect additional ports all have hierarchical names in the cell, which is a sign that they are incorrect, as the cell itself should not have any parents. The level of certainty about this fix is definitely not 100%, but it was tested on a hierarchical analog design, and setting levels of parasitic caps caused new nodes to appear in subcircuits and in no cases did information appear to be lost.

Got to the bottom of why area and perimeter values are no longer output for transistors. The problem came from a change made to fix an issue with capacitors marked as floating nodes because some nodes are not output as source or drain. But those nodes are output before the parameters, so when generating parameter output, all nodes appear to have already been output. Solution: Specify an additional bit in the "visited" mask for the node having been output that is separate from the mask for resist classes used by the code that writes parameter values, and use that bit as a test for whether the node is connected to some device (not necessarily a FET source or drain).

Changed the behavior of capacitance value output in ext2spice and ext2sim to make use of the new esSIvalue() routine, so that it no longer depends on a preformatted string. Corrected an issue where the esSIvalue() routine would output "a" for "atto" which is not supported by ngspice.

Made some changes to the way that ext2spice generates subcircuit ports, to avoid creating ports for node names that are redundant. It would probably be better to avoid creating the redundant node names in the first place; however, I am less certain why these are generated. The incorrect additional ports all have hierarchical names in the cell, which is a sign that they are incorrect, as the cell itself should not have any parents. The level of certainty about this fix is definitely not 100%, but it was tested on a hierarchical analog design, and setting levels of parasitic caps caused new nodes to appear in subcircuits and in no cases did information appear to be lost.

Corrected "ext2spice" to mark nodes on resistors from "extresist" so that they do not get marked as "FLOATING" nodes when writing out the parasitic capacitances at the end.

Got to the bottom of why area and perimeter values are no longer output for transistors. The problem came from a change made to fix an issue with capacitors marked as floating nodes because some nodes are not output as source or drain. But those nodes are output before the parameters, so when generating parameter output, all nodes appear to have already been output. Solution: Specify an additional bit in the "visited" mask for the node having been output that is separate from the mask for resist classes used by the code that writes parameter values, and use that bit as a test for whether the node is connected to some device (not necessarily a FET source or drain).

Corrected hierarchical SPICE extraction to reset the subcircuit name-to-number mapping used for the HSPICE format between subcircuits. Otherwise, subcircuits with the same instance ID remain in the table and may cause nodes to be output with a name that collides with other names in the same subcircuit.

Corrected an issue in which the device merging routine can generate NaN results for devices which are not FETs (specifically, devices that are declared using "msubckt" but are not FETs, although there may have been a related issue with non-FET devices not getting the correct M count), due to the device having zero measured width or length. NOTE: This may need more investigation. If a subcircuit device's method of merging cannot be understood, then such devices should never extract with "merge aggressive", and should always merge conservatively if and only if all parameters match.

Added extraction device type "csubcircuit", which should have been added a long time ago, since capacitors use a different method for calculating width and length than either transistors or resistors, so subcircuits need a special class designator or else the extraction may calculate the wrong dimensions for device width by totalling the perimeter between the device and terminal types, as it would for a MOSFET.

Got to the bottom of why area and perimeter values are no longer output for transistors. The problem came from a change made to fix an issue with capacitors marked as floating nodes because some nodes are not output as source or drain. But those nodes are output before the parameters, so when generating parameter output, all nodes appear to have already been output. Solution: Specify an additional bit in the "visited" mask for the node having been output that is separate from the mask for resist classes used by the code that writes parameter values, and use that bit as a test for whether the node is connected to some device (not necessarily a FET source or drain).

Separated drain and source records for the esFetInfo array, to support asymmetric FETs and other devices like bipolars that have three distinct terminals. This does not go as far as it should to make the array independent of the number of declared terminals of the device. However, it suffices to make, e.g., parameter "a2=area" work for a bipolar device, and to generate the right drain and source areas and perimeters for asymmetric (e.g., extended-drain) devices.
