writing vias. However, the underlying problem, which is that
stacked vias are not decomposed into their constituent parts, has
not been addressed. A "-units" option was added to the "def write"
command to force the units of the output file to be different than
the default of 1000 (nanometers). No checks are made for whether
values can be accurately represented at the specified scale.
the output to have an obstruction area over the entire cell except
for a keep-out area around each pin. Instead of marking every
part of the pin geometry, only the "chunk" (largest immediate
rectangle) surrounding the port label is output as part of port
LEF geometry. This avoids making unnecessarily complicated
abstract views, and makes it easier for other tools to read and
manage the same abstract views.
