on loading a layout to avoid doing so with in a suspendall ...
resumeall block. That avoids weird errors occurring when the
PDK toolkit scripts are run to generate a new device layout if
the top level layout is still (UNNAMED) and empty.
it as a single value "flags" (unsigned char) with meaningful flag
names. Added new option "-fail" to the load command to allow
magic to fail on loading a cell that does not have a corresponding
file rather than the default action of creating a new cell. Added
a flag for the "-quiet" option so that behavior on "-fail" can be
done quietly.
which had been changed a few months back to remove the individual
cell count and only list the top level cell. The behavior has been
changed a bit so that "list" returns values for the top level cell
only, but "listall" returns a complete list. "drc list count total"
gives the DRC count for the top cell, but "drc listall count total"
gives the DRC count for everything (probably not very useful).
Also: Implemented a behavior by request to automatically removed
the (UNNAMED) cell whenever a new cell is loaded and the (UNNAMED)
cell has not been modified.
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.
