of cell name dereferencing on file loads, where the cell load
subroutine call ended up with the wrong number of arguments,
resulting in an invalid pointer and a crash condition.
only at the time of running the command "load". But cells are generally
loaded only on an as-needed basis, so the dereferencing option must be
saved as a flag in the cell and honored whenever its subcells are expanded
or otherwise read at a later time.
rid of redundant port entries in subcircuits. There is still an outstanding
issue as to whether nodes and connections need to be recursively iterated
to the hierarchy bottom. The current fix corrected the test case. Also,
added a "-dereference" option to the "load" command to revert to the
original behavior of using only search paths from "addpath" when searching
for files to load.
a cell instance name not related to an array moved a variable that
was used later in the routine to the inside of an if block,
effectively making that variable undefined in most cases.
commit, found that DBTreeFindUse fails to find such uses because
it strips the array delimiters off the name. Fixed the routine
although the routine really should be checking if the use is a
1- or 2- dimensional array and stripping off only the components
expected. The current code will probably fail for cell uses
that have brackets in the name AND are arrayed. Fortunately
this search routine does not appear to be used frequently or in
any critical database functions like netlisting.
