not restored until after all cells have been processed through
extraction. Otherwise, top-down connections can end up with
different generated names for the same node, resulting in a
disconnect in the netlist.
extflat code; failure to provide a forward external reference
to EFHNBest() resulted in a failure to correctly evaluate a
boolean expression. That resulted in a failure to merge
hierarchical nodes during ext2spice, resulting in an incorrect
netlist with single nodes broken up into pieces.
change from passing the HierName to passing the HierContext (of which
HierName is a part) so that more information from HierContext (such
as the cell use being visited) can be passed to the callback
procedure (largely for diagnostic purposes).
with ext2spice without the hierarchy option. More work needed to
produce correct hierarchical output and to support extraction
devices other than the old "fet" record.
added a long time ago, since capacitors use a different method for
calculating width and length than either transistors or resistors,
so subcircuits need a special class designator or else the extraction
may calculate the wrong dimensions for device width by totalling the
perimeter between the device and terminal types, as it would for a
MOSFET.
