Issue with Skywater 130 Monte Carlo Mismatch Analysis

VLSI lab IITB

I’ve encountered an issue while running Monte Carlo mismatch simulations using the Sky130 PDK in Cadence. Even though all transistor dimensions are well within the valid limits defined by the PDK, the simulation fails and reports an error stating that the device dimensions are “out of the defined bound.”

It appears there might be a bug in the Monte Carlo mismatch model files for Sky130. Could someone please suggest a solution to it?
