gdsImport does not work for hierarchical gds #43

Closed muab closed 8 years ago

muab commented 8 years ago

gdsImport seems to work for a flat gds, but not for the same design when it's a hierarchical version which includes other subcells. the error is: Traceback (most recent call last): File "gds_tests.py", line 11, in amarks = core.GdsImport(myfile)#, verbose=2) File "/usr/local/lib/python2.7/dist-packages/gdsCAD-0.5.0-py2.7.egg/gdsCAD/core.py", line 2388, in GdsImport layout.add(c) File "/usr/local/lib/python2.7/dist-packages/gdsCAD-0.5.0-py2.7.egg/gdsCAD/core.py", line 1241, in add names=[c.name for c in self.get_dependencies()]

I found the issue. It was not related to flat or hierarchical gds. apparently it will crash when the cells have a name that include $ and = characters. This happened to me with cells that I had on the hierarchy, hence my erroneous assumption. If you change this names in the gds for underscore _ for instance, the import will apparently work without any problem, for flat and hierarchical gds.
