sky130-trng (2AMLogic)ECADConfidence: Medium

The extractor writes a 0.36 um nFET against a model whose smallest bin is 0.42 um and nothing in the extract report warns; ngspice aborted at parse after 2844 s of a 3480 s fleet slot, and consumers currently need a post-extract text rewrite, which is easy to get wrong.
