Abstract
In some embodiments, in a method, a layout of a circuit is received. A netlist with indicated pattern density (PD)-dependent mismatch elements associated with different PDs, respectively, is generated using the layout. A simulation on the netlist is performed such that when the PD-dependent mismatch elements are modeled in the simulation, corresponding model parameters of the PD-dependent mismatch elements are generated using variation distributions with different spreads.
