used when ob may be NULL. Added a check in front for ob == NULL.
Also: Changed the disconnected node alert so that it does not
mention nodes marked "port_mismatch_error". These are disconnected
by definition, will show up in the pin list, and printing them as
"disconnected pins" is just confusing to the end user.
should not be called after CreateTwoLists(). CreateTwoLists()
was being called in one case only to print the contents of the
cells, so that part was pulled out into a separate routine.
This fixes crash on macos due to wrong hash() being linked in.
It also makes sure that proper function defs are declared and available
(as required by C99) to make compile possible in newer compilers (e.g.
Apple clang) and to some extend prevent similar linkage issues happening
again.
Changed line breaks in log and stdout to better differentiate subcircuits.
Added merged series device counts and differentiated from parallel merged device counts.
Added file number to disconnected net, merged count messages.
Changed black box errors to show file numbers instead of hard coded values.
Final error cell list changed from all on one line to one per line.
Removed redundant display in black box warning.
with the file number, so that it can get confused between libraries.
Also made a fix to coerce one cell class to be forced to be the
same in both circuits under some circumstances.
that are not declared in the verilog netlist because they don't
connect to anything, and their presence is not required by verilog
syntax) and the printing of proxy pins created to act as placeholders
for those implicit pins. Also removed the pinting of the "disconnected
pin" messages for black-box modules (since by definition they have
disconnected pins, because black-box modules have no contents).
to include type CLASS_MODULE in the list of types to descend into,
since "module" (black-box) types need to be checked for pin
matching even if they have no contents. This allows two verilog
netlists to be compared against each other.
some problems stemming from comparing a case-sensitive netlist
against a case-insensitive one. Verilog netlist reading does
not yet have support for macros other than "`include", and it
does not yet have support for bit vectors constructed with
braces ({}).
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.
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.
been modified in the Tcl/Tk version to take an additional argument
for the file number. In the non-Tcl/Tk-compatibility mode, netgen
should operate in a backwards-compatibility mode with filenum = -1.
