Unify microcontroller and breakout board versions #389
Description
The current way to DRY out microcontroller ICs and their breakout board variations is kind of a cumbersome mess of multiple inheritance and fragmented classes. But with the recent feature to replace a block with a footprint, this can be cleaned up, creating the IC block internally for modeling but replacing all the internal parts with the module footprint.
See #367 for a concept.
Requirements:
- Needs a way to propagate pin assignments to the wrapper.
- Idea: preserve the grab-bag-of-IO abstraction in the wrapper, inspect into the internal pin mappings (pin name => pin number) to generate a mapping table for the wrapper module. Infrastructural block to handle this, takes in a dict of (chip pin name -> module footprint pin).
- Need a way to restrict mappable pins in the chip to those present on the module, perhaps pin mapper.allowed_pins
- Perhaps think about a way to support wrapper blocks instead of footprints.
