file writes by adding the path for each cell use, but being ignored
for file reads. The cell path saved in the .mag file is now honored
on read-back. If the cell needs updating, then the cell version
can be manipulated using "cellname filepath". No UI methods are
currently implemented for managing cell versions.
errors from the area checked must use the same area as is used
by the interaction checker to recompute errors. In earlier code,
both these areas were much larger than necessary. In the last
code update, the area to make revised checks was reduced, but
the area cleared of errors was not, resulting in errors that
would disappear from the layout as paint changes were made, until
a full "drc check" was run again. This code commit makes the
areas the same again so that no errors are lost.
much larger area than necessary to the interaction check, and
the other which failed to scale the tech halo distance down
after scaling all the rules. Both of these led to huge areas
of a layout being unnecessarily checked when even a tiny part
of the layout was modified. Corrected behavior matches
expectations for interactive DRC response.
that are longer than the formerly-fixed array size 256. This
conflicted with the recent addition of holding path data in
properties, where the path coordinates can be significantly
longer than the fixed array size. Same change as made to magic
version 8.1.
handling for grid subdivision. Scaled the value of "center"
for a CIF box and then attempted to use "center" as an unscaled
value. Same correction as made to magic-8.1.
to have come from an unfinished (or at least unchecked) development
effort on improving the checks for DRC interaction errors (which
also affects extraction).
a port so that repeated uses of "apply" won't fail because the
port number is already used. Corrected the "port remove" command,
which didn't work, and corrected the script to do "port exists"
before "port index" so that the latter won't complain if the label
is not a port. Same changes made to magic-8.1.
