Alternatively a possible outdated version is hosted here or here.

Current state

Most important functionality for handling layouts and netlists is already there. But this is still WORK IN PROGRESS and not stable yet.

Known shortcomings & ideas for future work

  • Provide a way to check if an ID is valid. For example with non-panicking .try_*() -> Option<*> functions.
  • Power domains: There's not a good way yet to represent power domains.
  • Region search: Implement region search as a decorator for LayoutEdit/LayoutBase traits.
  • Modification observer: Implement a decorator which allows to observe modifications on database structures using callback functions.
