Claim 5:
6. A system comprising:
a memory storing instructions; and
a processor, coupled with the memory and to execute the instructions, the instructions when executed cause the processor to perform operations comprising:
accessing a mask pattern for use in a lithography process that prints a pattern on a wafer; and
applying the mask pattern to a deterministic model of the lithography process to predict a characteristic of the printed pattern that is subject to local stochastic variations, wherein the deterministic model comprises (a) a deterministic compact model that predicts the characteristic of the printed pattern but does not account for the local stochastic variations of the characteristic, and (b) a deterministic correction to the predicted characteristic from the compact model that accounts for the local stochastic variations of the characteristic in the printed pattern.
