It looks like Cadence has "moved on" from supporting the
original layout-based PCells and is failing to evaluate?
That's pretty crappy. You might have too crusty a lib,
for the brave new modern world? Do you have access
to an older version that wasn't so unfriendly to legacy
libraries? Or, to some facility for converting layout
based PCells to SKILL based?
Have you tried to push-view into one of those instances
and see where it takes you, and what you find there?
