which instead of defining a device or subcircuit that exists inside
the cell, instead redefines the cell itself as a device or subcircuit
model that exists in the PDK. This is used where a specific layout
subcell has its own associated device definition in the PDK. Instead
of the "device" property value being the line that gets generated for
a device in the subcells .ext file, the property value should be the
word "primitive" optionally followed by any parameters that need to
be passed to the subcircuit call.
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.
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.
a scaling issue in extract) which was caused by the addition of
hierarchical netlist generation. Finding hierarchical connections
requires finding instances by name, so it is vastly better to create a
hash table of instances instead of a linked list.
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.
