Tim Edwards 35175882bc Corrected another similar bit of code causing a segfault. It is 
not known, though, why the flag is set indicating valid planes
in the clientdata record when there in fact is none.  That seems
to be the underlying bug.
 2020-05-08 17:02:36 -04:00
Tim Edwards 6737741902 Corrected CalmaRdpt() routine to avoid crashing if the cd_client 
record is uninitialized when calling the rescale routine.
 2020-05-08 16:44:29 -04:00
Tim Edwards 669ae1dfcc Added a way to subvert the adding of a prefix to subcells of a dumped 
GDS library from an abstract view, by defining the property LEFview
in the cell as "no_prefix" instead of "TRUE".
 2020-04-23 16:03:29 -04:00
Tim Edwards 0f16b7da6c One modification to the last commit, such that if the cell is not 
marked as abstract yet has GDS_START but not GDS_END defined,
magic will not crash by attempting to use the nonexistant value
of GDS_END.
 2020-04-23 15:08:56 -04:00
Tim Edwards 88e23a114e Corrected CalmaWrite behavior to be as was intended for handling vendor 
GDS of abstract views, such that if the cellname being dumped is the
same as the library name, then no prefix is added to subcells.  This
behavior may be changed in the future.
 2020-04-23 14:41:29 -04:00
Tim Edwards bcb8e9a081 Corrected typo in CmdCD.c for "count_total" when compiled without Tcl/Tk. 2020-04-18 15:49:23 -04:00
Tim Edwards 0a78dc0ab5 Updated revision to 3. 2020-04-14 11:08:29 -04:00
Tim Edwards 4b31af66b1 Corrected error in the bplane implementation that accidentally 
called the undo record generation twice when transforming (move,
copy, etc.) cell instances.  This would cause the "undo" command
to regenerate the old instance position in the bplane records,
generally causing trouble down the road (did not encounter any
fatal errors, but it can't be good).
 2020-04-14 11:00:51 -04:00
Tim Edwards 97df4e8dd1 Removed a diagnostic debugging message from the antennacheck routine. 2020-04-09 19:37:23 -04:00
Tim Edwards 116feec2df Found and added another unused but missing subroutine from the bplane 
implementation.
 2020-04-08 12:28:26 -04:00
Tim Edwards 2d35bb52b3 Updated VERSION to trigger overnight tarball and mirror. 2020-04-08 12:12:36 -04:00
Tim Edwards 99ac84d590 Corrected bpDump to remove UnitsS2I(), replacing with scalefactor 
determined by CIFGetOutputScale().
 2020-04-08 12:11:32 -04:00
Tim Edwards 7e1fcc8ef6 Fixed lefWrite, which was not including drc.h and so was messing up 
one of the arguments to the DRC technology query.  Also, drc/drc.h
itself did not export that particular function, so it was added.
 2020-04-07 20:08:42 -04:00
Tim Edwards 937e848d03 Modified DBTreeCopyConnect() so that it can take an argument to 
not copy labels;  not copying labels speeds up the antenna checks
(which don't need labels) greatly.  Also fixed several numerical
overflow problems in the antenna checks, which resulted in false
positive errors, as well as nonsensical results.

Tim Edwards 08fabeedd5 Merge branch 'master' into bplane 
Merging fix to "lef write" to preserve SITE, from master branch.
 2020-04-01 11:02:08 -04:00
Tim Edwards e98b768c45 Corrected "lef write" to add the SITE definition that it may have 
been preserving in the cell properties (which was inadvertently
omitted).
 2020-04-01 11:01:13 -04:00
Tim Edwards 706e342171 Merge branch 'master' into bplane 
Conflicts:
	lef/lefWrite.c

Merged change to "lef write -hide" method from the master branch.
 2020-04-01 10:46:06 -04:00
Tim Edwards d6cadeb0cd Decided that "lef write -hide" should always use widespacing rules, 
because otherwise all pins will flag metal-to-obstruction spacing
within the cell if the cell is wide enough that the obstruction
layer satisfies the width requirement for the rule.  It is too
complicated to try to find specific places where the wide spacing
might not be needed.  Potentially this could be a problem for
technologies that define a number of graded wide-spacing rules,
as the largest-width rule is always used now by "lef write -hide",
and the largest-width rule could theoretically allow enough space
to route through, which would cause a short that cannot be
detected.  That would be a pathological case that may not show up
in practice.

Tim Edwards daf93e5bad Merge branch 'master' into bplane 
Conflicts:
	VERSION

Merged from master correction that should prevent "lef write" from
creating pins with no geometry in them.
 2020-04-01 09:01:33 -04:00
Tim Edwards e296fc5ba0 Corrected an error in lefWrite that should have avoided degenerate 
labels by expanding a zero area label rectangle, but then if "select
chunk" returns nothing, it sets the area to the zero area label
rectangle instead of the expanded one that it just created.  This
is the reason that "lef write" is producing pins with no geometry
in the LEF file output.

Tim Edwards 195bb301ff Merge branch 'master' into bplane 
Conflicts:
	VERSION

Changed mallocMagic() argument to size_t to match change in master
branch (essentially an ineffectual change).
 2020-03-31 09:35:55 -04:00
Tim Edwards f689366553 Updated VERSION with commit. 2020-03-31 09:35:25 -04:00
Tim Edwards 688f07d302 Changed mallocMagic() argument to size_t. However, this is probably 
not useful so long as Tcl_Alloc() has (unsigned int) for an argument.
The more important investigation is probably to determine if there is
a way to keep csa2_list from growing to absurdly large sizes on
connectivity checks.

Tim Edwards d742550edc Merge branch 'master' into bplane 
Conflicts:
	VERSION

Merge from master (LEF read:  Read all tokens for LEF CLASS record)
 2020-03-30 09:37:42 -04:00
Tim Edwards b5e06455c5 Corrected LEF read routine so as not to truncate LEF "CLASS" to a 
single token (LEF CLASS records may have a subclass, such as "PAD
INPUT").
 2020-03-30 09:36:24 -04:00
Tim Edwards 42917e80cc Merge branch 'master' into bplane 
Conflicts:
	VERSION

Merged master (fix to dbcConnectFunc for integer size overflow in
call to mallocMagic()).
 2020-03-28 20:15:17 -04:00
Tim Edwards 70613a3778 Modified line in DBconnect.c to cast csa2_size to type (size_t), as 
magic crashed when the conSrArea array exceeded the size of a 32-bit
int during the antenna rule check.  Should be good for another four
orders of magnitude.

Tim Edwards aab318176b Corrected lefWrite, which was not initializing the count of items 
written, so that a LEF output with no ports would fail to write
the OBS ... END around the obstruction geometry.

labels with the same text.

 2020-03-25 11:23:16 -04:00
Tim Edwards 195e096d64 Modified lefWrite to ensure maximum spacing per all widespacing rules 
for any gap between a pin touching the cell boundary and the internal
obstruction layer.
 2020-03-25 11:07:54 -04:00
Tim Edwards 6bae7c25c4 Enhanced the "lef write -hide" command option to check for metal 
wide spacing rules; should result in LEF views that can import
back into magic without DRC errors.
 2020-03-25 09:29:16 -04:00
Tim Edwards 007806521c Updated the "lef write -hide" to understand and use widespacing rules 
(may still need additional enhancements, as it does not specifically
look for layer-to-obstruction rules).
 2020-03-25 09:25:32 -04:00
Tim Edwards 5bf2a6ec69 Updated VERSION to revision 202. 2020-03-24 13:59:03 -04:00

Tim Edwards fe727cc6f2 Found that the "crash save" command in tools.tcl also disrupts 
redirected command-line entry from the layout window;  fixed.
