function that was available in versions 7.1 and earlier that
allows the use of the command "erase errors" to remove DRC error
paint (only when the DRC checker is off, of course).
This correction allows a full path to be passed for the cellname
and will (correctly) break the path into cell name and path
components (previously was naming the cell with the full path).
To avoid name conflicts, the cell name gets modified if the path
cannot be resolved against an existing cell of the same name.
enabling the "plow" command. At this time, however, not all
rules are being implemented correctly given the numerous changes
to the DRC handling since the last time "plow" was working. Fixes
are ongoing.
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.
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.
from "gds polygon subcell". Previously both polygons and paths
were put into subcells named polygonXXXXX (substitute numbers
for XXXXX). Now polygons go into cells named polygonXXXXX and
paths go into cells named pathXXXXX. This makes it easier to
keep track of the original path. NOTE: The path centerline
should be kept as a cell property in this case, and the path
options like endcap style can also be held as properties. The
polygon boundary should be treated similarly.
avoid the problem where subcells violate DRC themselves but do
not violate DRC in the context of the parent (i.e., the parent
adds metal to avoid minimum area error), DRC errors in subcells
are neither counted nor displayed, but they remain present in
the subcell database. The DRC check enumerates all subcell
errors as mandatory check areas in DRCFindInteractions(), so
that those areas are always counted with the interaction areas.
Previously, if a subcell violated a DRC rule by itself, that
error would be counted and displayed in the parent even if the
parent had paint causing the error to no longer exist.
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.
