klayout-tools (2AMLogic)VerificationConfidence: Medium

Signoff only accepts a SPICE run as evidence. A spec row checked by an analytical model in Python "reads as uncovered although its evidence exists, and nothing in the manifest ties the record to the row." The bad workaround would be wrapping the model in a dummy SPICE netlist "which would pass without testing anything."
