Tim Edwards a3b61abe2b Corrected an error in which "extract unique noports" and

an attempt some time ago to avoid issuing warnings about shorted

request #325 from Daryl Miles.  Made a few simple style changes
to conform to (what is vaguely defined as) the overall programming
style for magic (passed down from John Ousterhout).

2024-10-01 12:36:12 -04:00
Tim Edwards 155f19a6d8 Corrected an issue causing a crash condition when using "extract
unique" on a flattened layout (some labels end up NULL and the
NULL condition needs to be checked).  Also remembered to update
VERSION, which was missed on the last commit.
2024-08-04 11:37:54 -04:00
Tim Edwards fd2b1eb9ee Added code that when running "extract unique" always prefers to
change a non-port label name instead of a port name whenever it
finds one of each with the same text on different nets.
2024-05-07 16:20:35 -04:00
Tim Edwards 0ae54b500a Added the ability to track the first CellDef to fail to read and
report it after "Failure to read in entire sub-tree".  This will
not report every failing cell (since it quits reading after the
first failure) but will avoid the existing issue of printing
nothing and leaving the user with no feedback as to which cell
was the problem.
2024-04-29 17:43:37 -04:00
Tim Edwards 22ea7a924f Corrected an extraction error that can cause an infinite loop
depending on the order of extraction devices.  Specifically, the
case of a source-drain tied FET was breaking out of a loop when
it should have been breaking out of a double loop.
2023-10-27 14:32:44 -04:00
Tim Edwards 7a9445ec30 Corrected the extraction offset, in which a parameter like "l"
can provide a delta offset such as "l+0.06", indicating that
the extraction model has a length larger than the drawn device.
Previously the value was assumed to be in microns but did not
scale between the .ext file and the SPICE netlist.  Corrected
so that it scales like the other parameter values, being
converted to internal units and tracking the internal grid
scale.
2023-10-24 20:29:04 -04:00
Tim Edwards 5b29870fce Corrected an extraction issue in which an error message about
"unexpected asymmetric device" is printed prematurely, as it
is inside a loop checking over all device entries compatible
with a device type.  Also:  Flagged an issue with the "label"
keyword in the "cifinput" section of a tech file.  The "label"
keyword cannot be used in conjunction with boolean operators.
It can only connect labels on a specific GDS type to one magic
type.  Unfortunately, because this was not flagged before as
an error or warning, the incorrect usage has crept into a lot
of tech files.  This uncovers an underlying issue that labels
must be allowed to automatically reconnect types, which is
undermined by the "no-reconnect-labels" cifinput option.  That
issue will be addressed in an upcoming commit.
2023-10-16 17:29:05 -04:00
Tim Edwards 7e5dbd17cd Fixed another issue in which sticky labels on a non-electrical
type (like "comment") show up as nodes in the .ext file, which
they shouldn't.
2023-09-22 16:03:53 -04:00
Tim Edwards 952b20d2a2 Corrected an issue where code expected sticky labels to be at the
front of the list during extraction, except that after copying
they're not.  Removed the expectation, although that causes the
entire linked list of labels to be parsed and may cause excessive
run-times in pathological situations.  Keep an eye out for
unintended consequences.
2023-08-01 13:59:46 -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
Johan Euphrosine 96eb275622 quick and dirty emscripten port 2023-07-12 00:31:37 +09:00
Tim Edwards b899a500d5 Added a new method to the extraction which allows parameter limits
to be declared for each device model, so that different models can
be specified for different parameter ranges.  For example, this
will simplify the definition of the high-sheet-rho poly resistors
and the bipolar transistors in sky130 by removing the need for ID
marker layers;  it also allows the correct device model to be
extracted when reading data from GDS that does not contain the
extra (and not foundry-approved) ID markers.
2023-07-06 12:35:47 -04:00
Tim Edwards ca469510d5 Found that extNodeName() prefers the first name in a region's label
list for output, but that the code in ExtRegion.c does not sort a
region's label list to keep ports at the beginning of the list.  So
any net with multiple labels may end up with a non-port label as
the name of the node, which eventually becomes the name of the port.
A quick fix keeps these lists sorted.
2023-06-27 15:35:57 -04:00
Tim Edwards ca985edbd0 Corrected a typo in the previous commit that causes parameters to
be output twice for scaled devices (such as diodes in the sky130
process).  Above and beyond the typo, though, the implementation
of offsets is not very well thought out and needs to be revised.
For one, the +/- notation can be confused with signs in the
parameter expression;  that is also fixed in this commit.  But
there is currently no way to express both a scale and an offset
for a device parameter.
2023-06-23 08:39:59 -04:00
Tim Edwards 07267dc126 Extended the device parameter notation to include offsets using
'+' and '-' in the same way that '*' is currently used for specifying
a parameter scaling.  The combination of a scale and offset for the
same parameter has not (yet) been implemented.
2023-06-21 20:44:38 -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.
2023-06-14 13:55:59 -04:00
Tim Edwards 9b131fa96c 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.
2023-06-13 17:14:36 -04:00
Tim Edwards 5300f322de Added code to calculate area and perimeter of layers that are not
on the same plane as a device identifier layer.  This (finally!)
allows proper calculation of area and perimeter of diodes and
bipolars, for example.
2023-06-09 15:31:58 -04:00
Tim Edwards 6caab5da37 (1) Corrected an error with extraction in which terminal area and
perimeter are not initialized, and if a terminal perimeter/area
calculation is missed (which is happening on devices with terminals
in planes other than the plane of the identifying type), then the
perimeter/area of a previously handled device will get output.
(2) Corrected an error with "flatten -inplace" in which the command
fails to deal with instance arrays.
2023-06-07 08:06:18 -04:00
Tim Edwards 79dc621626 Added a warning message if attempting to extract an empty cell,
so that it is not so mysterious as to why no output was generated.
2023-04-28 09:24:04 -04:00
Tim Edwards a33d7b78b5 Corrected an error in search for substrate under a device. If
"space" is considered part of the substrate, then the check for
planes to search should exclude "space" from the type mask
first.  Otherwise, all planes get searched, not just the substrate.
Also:  The same routine can falsely flag a device terminal as
substrate if a split tile is marked as the device's region.  This
was also fixed.
2023-04-24 17:30:40 -04:00
Tim Edwards c1f4555ba0 Corrected behavior of "load ... -dereference" to bring back a
previous behavior that had inadvertently been changed.  In recent
versions, "load <absolute_path> -dereference" would incorrectly
apply the dereferencing to <absolute_path> rather than just its
subcells.  Cleaned up the code around DBCellRead() in the process,
so everything is more straightforward (although probably more
could be done in that regard).
2023-04-18 11:01:58 -04:00
Tim Edwards cff2b97678 Changed the default extraction options to include "do aliases" by
default, since not setting it can have unfortunate consequences
for cells that don't declare ports and have multiple conflicting
labels on a node.
2023-04-16 12:18:16 -04:00
Tim Edwards 1d8fcca09b Implemented a change to differentiate between "sticky" labels and
labels that are not connected to their declared layers.  It's the
latter type that need additional processing in ExtSubtree.
Limiting this processing significantly cuts down on processing
time when there are many labels in a layout, as happens with the
"def read -labels" command option.
2023-04-06 12:26:18 -04:00
Tim Edwards 8fb96db14c Found one additional issue in the extraction that causes incorrect
partitioning of unshielded areas reaching outward from any given
edge, caused by using a boundary value in the 2nd recursion call
that had been modified for the 1st recursion call and so was no
longer valid.
2023-03-24 17:11:27 -04:00
Tim Edwards 30184cb506 Finally tracked down several bugs in the sidewall walking routines
that had been causing negative capacitances to substrate to be
generated for certain complex geometries.
2023-03-24 09:51:22 -04:00
Tim Edwards d8f926865d Modified the behavior of cell reading, mainly with respect to
dereferencing, and making the behavior of "load" on the command
line (i.e., loading a cell from a file) the same as the
behavior of loading a cell as a result of expanding an unloaded
instance.  In both cases, if "load -dereference" is used, and
a cell does not exist in any search path but does exist in the
original location, without dereferencing, then the cell will be
loaded from the original location.  Also:  Corrected an error
that has existed since adding the capability to read compressed
files, which causes magic to crash when attempting to run the
"crash recover" command (because that routine was mixing
compressed and regular file stream calls).
2023-03-20 21:00:35 -04:00
Tim Edwards 10448788f9 Found another error causing negative capacitances and fixed it,
but the search continues for another mechanism that continues to
do the same thing.
2023-03-17 21:59:47 -04:00
Tim Edwards ca0cb1322a A couple of corrections to the last commit, where the equation for
computing the amount of fringe shielding was wrong.  This fixes
one of my example cases, but not the other one, so I still need to
pin down a condition that can result in negative capacitance.
2023-03-17 20:47:08 -04:00
Tim Edwards edb05fb3d1 More corrections to the method of calculating fringe capacitance
inside a halo area.  The previous implementation used a linear
accounting of error to determine the amount of shielding, but
since the shielding is nonlinear, this is a poor approximation
and regularly overestimates the shielding and leads to negative
capacitances.  The corrected method makes many more calls to
the atan() function and the performance impact for extraction
will need to be evaluated.
2023-03-17 13:51:33 -04:00
Tim Edwards e9d434597a Corrected issue with the commit of version 8.3.378, which can
cause a crash when extracting some devices like bipolars with
terminals on different plance.
2023-03-15 14:36:15 -04:00
Tim Edwards 913c830dee Corrected the extraction of length and width of devices that are
(truly) missing a terminal (such as a MOSCAP made with a gate
extending into but not crossing a diffusion region).  Added the
most requested GUI feature, which is a vertical scrollbar on the
parameterized device window (could be improved by maximizing
window height without exceeding display height).
2023-03-12 16:57:47 -04:00
