if a GDS (CIF) layer is dependent on, and only on, a templayer or
layers that get hierarchically processed, it will not get added to
the list of layers needing hierarchical processing, and therefore
end up not being generated in the output.
options "text", "port", and "noport" in the techfile. The
incorrect interpretation was preventing backwards compatibility,
such that ports would not be output on GDS layers if the "port"
option was not used.
window to change after hiding a layer using the toolbar and then
refreshing the layout. Fixed by saving and restoring the graphics
state around the routine that configures the toolbar image. Also
added a check to CifPaintCurrent to guard against using an unassigned
ClientData record as a pointer (causes a crash), and added braces
around "expr" values in the Tcl wrapper, which reportedly results in
faster execution of the expression.
"port" and "noport" in the cifoutput section to distinguish
between layer:purpose pairs for port text vs. other kinds of
text. This allows a closer correspondence between GDS read and
write. Note that the port writing is currently only in the GDS
write routine, not in the CIF routine.
This allows text appearing on a specific GDS layer:purpose pair
to be interpreted as a port. This does not quite match the
intended behavior of such layers, since it is implied that any
layer geometry coincident with the text should form the area of
the port, which is not (yet) handled. Also, it is presumably
implied that the port order matches the order in which text
appears in the GDS stream, but magic does not preserve this
order when re-writing any GDS output.
magic conversion for making magic contact types from contact cuts
from the CIF/GDS input rules rather than the output rules. This
generally makes more sense, plus avoids conflicts where the output
rules may be set for CIF-DRC checks and may not be appropriate for
LEF input without changing the style.
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.
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.
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.
