Tim Edwards 22fbb28656 Corrected one major error which will cause magic to fail to find the
".res.ext" file from "extresist" after using "extract do local" (and
probably with "extract path" as well).  Fixed this, and also made
sure that "extresist" writes the ".res.ext" file to the same location
as ".ext" always, so that handling is consistent throughout the
full R-C extraction process, across the use of "extract", "ext2sim",
"extresist", and "ext2spice".
2023-08-06 16:53:07 -04:00
Tim Edwards 89f1c4ee67 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.  Also:  Corrected a crash
condition when using "extract path <name>" when directory <name>
does not exist.
2023-07-28 09:40:41 -04:00
Tim Edwards 081058a41b Corrected an issue in which ports which have the same name under
the assumption of case insensitivity (e.g., VSS, Vss, and vss)
are kept separate even when writing SPICE netlists, which are
case insensitive.  The code fix both avoids flagging these ports
when running ext2spice, and more importantly, allows the use of
"ext2spice short" without these ports ending up separate in the
output netlist.
2023-07-08 12:14:57 -04:00
Tim Edwards 482d7534a2 Reimplemented the "extract do local" option as "extract path <name>"
with "extract do local" now being equivalent to "extract path .".
This allows extraction files to be put in a subdirectory and not
clog up the current working directory.  Also:  Fixed some behavior
around the use of "ext2spice -p <path>" so that it (1) works, and
(2) is compatible with the new "extract path".  Since the ext2spice
and ext2sim commands are effectively independent of the primary
extraction, the "-p" option is needed to correspond to the use of
"extract path".  Hopefully this is seen as only a minor inconvenience.

Tim Edwards fc62a63d41 Corrected errors in the extresist code and in extflat, both of which
can result in negative resistors due to integer overflow.  In all
cases, the target was floating-point and it was only necessary to
recast everything to float first.

Tim Edwards 65ef9a1ad3 Final (I hope!) corrections to the "def write" command. 2022-11-19 22:02:44 -05:00
Alessandro De Laurenzis b306a39560 Compatibility with C99 standard
This commit makes the code (mostly) C99-compatible, enabling to compile
it without the -Wno-error=implicit-function-declaration flag. This
way, Magic becomes usable on arm64 architectures, specifically on Apple
computers with M1/M2 SoC.

Tim Edwards 468a8ae0be 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.
2022-05-04 16:43:38 -04:00
Tim Edwards fcc884332b Made some corrections to the "extresist" code to avoid issues with
extracting a port-to-port net that does not touch any devices.
The error happens in a fairly rare set of cases.

Anton Blanchard 73fee3e5fd Add missing types in function prototypes
It would be nice to convert the codebase from K&R to ANSI function
prototypes, but for now just clean up the warnings.
2022-01-10 14:04:37 -05:00
Tim Edwards 9a17539ca7 Corrected the use of EF_SUBS_NODE to distinguish between device
substrate (bulk terminal) and global substrate.  Otherwise, the
routine in ext2hier.c that finds the substrate node will find the
first device bulk connection, not the default substrate.

Tim Edwards bd59849309 Reverted a line in EFread.c back to the way it had been before
magic version 8.1.154.
2021-09-28 22:07:58 -04:00
Tim Edwards 6136d3ff0f 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.
2021-07-10 21:13:24 -04:00
Tim Edwards fc9ecd2c9b Corrected a problem with an uninitialized entry in ExtCurStyle that
could cause serious errors on systems that do not auto-zero allocated
memory.  Also:  Fixed an error introduced by a recent commit to allocate
character memory for efReadLine() which frees the memory before reading
a .res.ext file, causing a crash when using "ext2spice" with the
"extresist on" option.
2020-06-05 12:46:46 -04:00
Tim Edwards ac244109bc Modified the efReadLine() routine so that it dynamically allocates
memory for the input line instead of using a fixed 1024-character
buffer.  That avoids the issue of rare but possible overflow when
reading a .ext file with unknown line lengths.
2020-06-03 21:57:56 -04:00
Tim Edwards efe6af8465 Modified the EFread routine so that it will not infinite loop on
a truncated line.  There is still a question as to why an example
occurred that caused a line to be truncated, and whether a buffer
size needs to be made larger or made dynamically allocated.
2020-06-03 20:36:12 -04:00
Tim Edwards 28d8808c65 Corrected several improper uses of StrDup() that used the first
argument as a pointer but also set the same variable to the
return value.  This is ambiguous, because the behavior depends on
whether the value being set upon return is the original value or
the reallocated value.  The result is system-dependent behavior.
2020-05-28 17:09:03 -04:00
Tim Edwards 2af38a4191 Updates from running the fix-ending-whitespace script. 2020-05-23 17:13:14 -04:00
Tim Edwards afe38c55c8 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.
2020-01-13 12:58:04 -05:00
Tim Edwards d0f3aaeb59 Corrected ext2hier.c so that resistance output from extresist takes
the right argument type (float, not int).  Otherwise all resistances
from extresist come out zero when doing "ext2spice extresist on"
and "ext2spice hierarchy on".  Also changed the format of the resistance
in the SPICE output to type float, since values are in standard units of
ohms, and rounding to the nearest ohm seems excessively coarse-grained.
2019-12-16 09:55:11 -05:00
Tim Edwards fd737dbf80 Overhauled the extresist code (again), this time to (1) correct for
a long-standing error (introduced with the "extresist geometry"
option) that can cause nets not to be extracted (due to the first
record not having extraction data, which was itself a long-standing
error in the code but which was not fixed correctly);  (2) handle
"device mosfet" type transistors (previously only handled the old
"fet" type extraction devices);  and (3) correct for the res.ext
file having a different scalefactor relative to the .ext file.  The
latter item was solved by forcing all input to scale like
ExtCurStyle->exts_unitsPerLambda, locally correcting all input as
needed.  Note that extresist still needs to handle other extraction
devices (e.g., resistors and capacitors) but those will require
additional handling in the routines which analyze the current path
to determine how to break up wires into paths.
2019-12-08 17:37:48 -05:00
Tim Edwards a4ea827d1e More corrections to extresist, which now appears to work if used
with ext2spice without the hierarchy option.  More work needed to
produce correct hierarchical output and to support extraction
devices other than the old "fet" record.
2019-10-28 13:10:16 -04:00
Tim Edwards b493334c73 Preliminary changes to support extraction devices other than the original
simple FET device in extresist.  Also:  Extended the bloat-all CIF operator
again, allowing the trigger layer for the bloat operation to include both
CIF layers and magic layers (previously only magic layers were supported).
This extension is possible due to the previous extension allowing the
trigger layer and bloating layers to be on separate planes.  This operator
extension is useful for tagging geometry that is in the proximity of, but
not overlapping, geometry on another plane.
2019-10-17 16:21:56 -04:00
Tim Edwards 53078588ae Changed the size of argv[] in efReadLine() to be 128 instead of
64 because I overran the 64 array with too many resistclasses in
a techfile.  This really should be dynamically allocated;  this
requires parsing the line to count tokens and reallocating as
needed (to be done).
2019-06-06 14:53:07 -04:00
Tim Edwards 9f5936c7cb Found an additional scaling-up problem in ext2spice (previously handled
a scaling issue in extract) which was caused by the addition of
hierarchical netlist generation.  Finding hierarchical connections
requires finding instances by name, so it is vastly better to create a
hash table of instances instead of a linked list.
2019-02-07 10:54:07 -05:00
Tim Edwards 7dc15a7d28 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.
2018-10-30 16:19:20 -04:00
Tim Edwards 79a3934d40 Corrected an error that was previously assumed to be fixed in
8.2.74.  Top-level port names are now flagged independently of
any subcircuit port, so they are easier to identify when determining
naming precedence for the net.  This makes the code cleaner and
removes the problems arising from non-top-level ports and global
names overriding the subcircuit port names.
2018-10-29 17:29:15 -04:00
Tim Edwards ca67c8aedf Added code to EFread to make sure that reading .ext files is
symmetric with writing them.  Since the writing of .ext files
was changed to preferably use the location of the cell being
read, and since the extflat database does not save this path
information, it was necessary to check the main database entry
for each cell to determine if there is a non-default path where
the .ext file may have been saved (with the current working
directory used as a fall-back if the directory is not writeable).
2018-09-25 14:19:30 -04:00
Tim Edwards 088fc759c4 Set of changes updating version 8.2 to the level of 8.1, since 8.2
development had been halted since it was first created back in April.
Version 8.2 is now the official development version, with the first
development push to create a Cairo graphics interface.
