overhaul was to introduce the concept of a "connection point"
between two cells to the ".ext" file format so that it becomes
possible to do proper hierarchical R-C extraction. Previously
this information was not kept in the .ext file, making it
impossible for "extresist" to know what sub-net of a net connects
up or down the hierarchy. However, additional changes were made
to the extresist code (in the resis/ directory) to add the
handling of connections up and down the hierarchy, and to make
the code a lot clearer and fix ambiguous variable and subroutine
names.
simple FET device in extresist. Also: Extended the bloat-all CIF operator
again, allowing the trigger layer for the bloat operation to include both
CIF layers and magic layers (previously only magic layers were supported).
This extension is possible due to the previous extension allowing the
trigger layer and bloating layers to be on separate planes. This operator
extension is useful for tagging geometry that is in the proximity of, but
not overlapping, geometry on another plane.
