  even using volare to get the very latest gf180mcu PDK version, I still see the pcells throwing python errors:

  ERROR: TypeError: 'builtin_function_or_method' object is not subscriptable in PCellDeclaration.produce

  Does the install bundle not state which
  dependencies and versions?

  If not, then you should put that question to
  the maintainers.

  However the error I see, looks more like
  maybe a PCell:code_pile sync / content
  problem, it seems a bit of code has asked
  for a nonexistent feature. Is the new code
  bad, is the PCell stale (or the other way
  'round)?

  Maybe take another cut at it from a blank
  slate and let the compile dependency checks
  / fails lead you, without the existing "clutter
  base"? Pull libraries at the same vintage, etc.

  Hi @ckarnstedt,

  this isn't the right place for this question, as this forum is not about the open PDKs.

  From what I know, these open PDKs currently need GDSFactory 7.x and will not work with later versions. The KLayout PCells apparently are in "low maintenance mode" and AFAIK there is work ongoing to fix the GDSFactory issue.

  The best place to look for support is the FOSSi chat: https://fossi-chat.org. There is a room for open PDKs.
