No AI resolution.
The NULL added is cdata which looks to be opaque callback user-defined-pointer,
this is not used in the method printPropertiesFunc() as a possible 3rd argument.

which prevents the "Ctrl-P" key from raising the .params window;
the underlying error is that the original error in the "property"
command was a disagreement about where "argstart" is placed. The
command was fixed to make the "property" command work correctly.
However, the solution made "argstart" wrong when using the command
"cellname property". Now both uses are handled correctly.
added fairly recently when getting rid of crashes related to
commands operating on non-edit cells. The lack of a cast was
prevening compilation on systems with more rigorous error
checking.
Previously, a file path beginning with "/", "./", or "../" would be
searched for verbatim and no searching would be done over paths.
This behavior now occurs for a leading "/" only. File paths with
"./" or "../" will search for the file with the path verbatim, then
proceed to search for the file with each search path prepended to
the filename as usual. This solves a problem for reusable, non- PDK
IP blocks, where the IP block may have an abstract view pointing to
a GDS file which is specified as being located at "../gds/<file>".
This file would not be found if the IP block was included into
another project. Now it can be done if the path to the IP is given
by "addpath".
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.
the same: (1) If the inodes of the filename are the same, then the
cells are the same. This avoids treating symbolic links as
different paths with different files; (2) If both layouts are in
git repositories and the git repository commit hashes are the same,
then the cells are considered to be the same. This allows projects
to be cloned into other projects as dependencies and used in
multiple places without magic treating them as different layouts.
assign the result to anything, causing later uses of variable
"lobj" to have an unitialized value and potentially causing a
crash condition. Thanks to Risto Bell for pointing out the
error.
some of the "select" command syntax; the code change caused the
"select top cell" command to behave the same as "select cell".
There was no specific code for handling "top", so now there is.
that no nets will be checked for antenna gate and diffusion area,
and no antenna properties will be output to the LEF file. This can
greatly speed up LEF output file generation for a large design.
Thank you to Tamas Hubai for the code patch.
in the .mag file "properties" list are not handled as being in
database units during .mag file reading and writing (although they
do track internally), making them subject to being scaled incorrectly
and change between a read and a write. Thanks to Sylvain Munaut for
identifying the problem.
is erased. In cases where magic would previously unattach the
label from the material and attach it to "space", now magic will
instead adjust the size of the label to stay entirely on the
material. That avoids a common error of losing label or port
connections when the material is trimmed back. Thanks to Philipp
Guhring for suggesting this implementation (github issue #305).
a transistor's first tile record is a well or substrate type;
normally this is avoided, but if that's the only device terminal
that connects to the node, it will be used. Also changed the
code to not report a failure when space is found under the
device, when space is allowed as a substrate type. Instead it
will print a message that the substrate is not being extracted as
a resistive network. However, note that the correct solution is
to do what the regular "extract" code does, which is to paint the
substrate type in the cell area first, so that there are valid
tile types to use for extracting the substrate network.
a .mag file to include the original system path. This restores the
ability to find the tech file for any cell created using the old
SCMOS technologies. This method is as problematic as is the way
all SCMOS tech files used the same name "scmos". But at least it
preserves backwards-compatible behavior (behavior prior to 8.3.471).
This commit corrects github issue #306.
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.
non-Manhattan geometry is analyzed for resistance extraction.
This patch merely prevents the crash condition. It does not
solve the root of the problem, which is that split tiles can
belong to two different nets, but the tile can hold extraction
information for at most one of those nets.
reduce the amount of redundant painting done by the connectivity
search algorithm, but which was preventing composed types (such
as FET gates) from getting added to a net if one of the composing
types (such as poly) was drawn over the device in an ancestor
cell. Removing the "if" statement does not appear to have any
significant performance impact, so this change is being adopted.
argument. For interactive magic in the Tcl/Tk wrapper, the
"-nowindow" option was appended to the command line. But for
Tcl scripts on the command line, all arguments following the
script name are considered arguments of the script. So the
"-nowindow" argument has to be inserted at the beginning of
the command line as the first argument after "magic".
method of messing with the argument count when using qualifiers
like "less" and "more". Now it keeps a separate count of the
number of non-qualifier arguments.
previously, MASTERSLICE layers would not be added to obstruction
layers made by "-hide". However, an nwell, for example, that
stuck outside of a prBoundary *would* be recorded, which was
inconsistent. Resolved this by allowing MASTERSLICE layers
in the OBS block, but only for layers that are not a substrate
type. NOTE: It may be better to just insist that a MASTERSLICE
layer define an obstruction type in the "lef" section of the
tech file, and treat it like routing obstructions. Alternatively,
one may question whether special obstruction types are needed at
all, as one could simply define an obstruction as a type without
a port label.
completely implemented for the "cifwidth" and "cifspacing" rules,
resulting in those rules being Manhattan distance checks. Finished
the implementation (duplicating code from DRCbasic.c, with
appropriate scaling to CIF coordinates).
contains brackets which are not indicating a cell array. Also
fixed a related issue with the PDK toolkit code, in which the
gencell routines fail if an instance name contains brackets which
are not indicating a cell array.
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.
