leading '/' of pin names and therefore failing to print anything;
(2) Corrected 'addproxies', which was ending abruptly at the end of
a circuit's object list, such that if an instance needing proxy pins
added was the last object in the circuit, it would not get the proxy
pins added, and therefore would fail LVS.
"permute default" by (1) handling the usual case for MOSFETs
(resistors and adding in parallel not yet implemented), and
(2) being done automatically when no setup script is specified.
include calculations of effective width due to the addition of
width of multiple device instances in parallel. The original
behavior of splitting all "M=" devices into individual instances
has been effectively inverted, instead combining all parallel
devices of the same class into one, with multiple property
records for devices with non-matching properties (e.g., width,
length, etc.). Property matching combines devices with different
"critical properties" (e.g., FET gate width) if these are defined
in the setup using the "property merge" command.
Not yet done: Matching of multiple property records when
critial properties are not defined, handling of critical properties
that combine in parallel instead of simple addition, handling of
devices that combine in series, and the combination of non-critical
properties (e.g., source and drain area, although these are usually
removed from matching).
errors at the end of LVS. The result of "verify matching" got
overwritten by the result from matching pins, erasing the information
about a cell having property errors.
comparisons between, duplicate cells (cells with the same netlist
that may have more than one name in a circuit, or which for some
reason appear with the same name more than once in a netlist).
Added more checks to the list prematching, which prevents various
troubles with cells having a mismatched hierarchy. Added a
command option to "flatten class" to flatten instances only within
a specific cell. Corrected one error in the pin matching routine.
Added a check in the pin matching routine to look for pins that
have been found to be no-connects after cleaning up the pin lists
of the children of that cell.
