When doing the layout of a poly resistor, are there any rules regarding poly/drawing not covered by poly/res? Is there a minimum length for such contact areas?

See https://skywater-pdk--136.org.readthedocs.build/en/136/rules/periphery.html#licon rules licon.1b and licon.1c, and https://skywater-pdk--136.org.readthedocs.build/en/136/rules/periphery.html#rpm . If you want properly drawn resistor layouts, use Magic.

Hi Tim, thanks for the info.
