Abstract:
1. A yield evaluating apparatus, comprising: a spatial correlation module, for receiving at least one process-related data and a plurality of circuit layouts, wherein the spatial correlation module obtains a spatial correlation coefficient between unit elements in the circuit layouts according to the at least one process-related data and calculates a spatial correlation between elements in each of the circuit layouts according to the spatial correlation coefficient, and the spatial correlation module selects one of the circuit layouts according to the spatial correlations; and a random sampling point generator, coupled to the spatial correlation module, wherein the random sampling point generator performs a random sampling to the circuit layout selected by the spatial correlation module to generate a plurality of testing circuit layout samples, and the random sampling point generator tests the testing circuit layout samples to evaluate a yield of the circuit layout selected by the spatial correlation module; and a computer, for implementing the spatial correlation module and the random sampling point generator.
