information for a non-matching pin in circuit1 and generates a
proxy pin in circuit2---there is some case where this is redundant,
I think, but I need to find the example.
saying that pins were mismatched when pin matching was never run
accidentally resulted in pin matching not being applied to black-box
entries. This has been corrected.
continues to allow missing pins to match unconnected pins, but
*only* on subcircuits below the top level. This essentially forces
layouts to separate merged pins with metal resistors, although
there should be an option in magic's ext2spice routine that allows
"equiv" statements, when declaring equivalence of two ports, to be
replaced by a zero volt source or zero ohm ideal resistor.
pins on non-black-boxed circuits as it does not black-boxed circuits,
but specifically looking for pins that are disconnected on both sides,
since those do not appear in the node list and are not otherwise
handled. Otherwise, disconnected pins will appear to have disappeared
from the first netlist.
a final parallel or series combination needs to be done but there
are still multiple property records. The multiplier was being
incorrectly applied twice, causing an automatic mismatch in
parameter values.
of multiple devices during flattening, that will skip over a node
record at the end of a subcircuit call being flattened and therefore
remove it from the netlist.
list that it prints in the side-by-side element mismatch comparison
for an element, when there is no node record associated with the pin
connection. This makes the output clearer.
swapped, so that if pin names are swapped on the top level, netgen will
report this as a final error message. Otherwise, the mismatch is only
reported back in the pin list where it is not obvious.
The algorithm is to run without exhaustive subdivision until the
last step because this is much faster. The final iteration must
be run with exhaustive subdivision on, or else it is possible to
have cells with swapped pins matching. The routines that resolve
automorphisms were setting exhaustive subdivision for the final
iteration. But simple "run converge" and "run resolve" were not.
