Abstract
This application discloses a computing system implementing a parasitic extraction tool to generate parasitic netlists from tests cases including test layout models of integrated circuit structures. The test cases include reference netlists corresponding to intended parasitic netlists for the test layout models. The computing system can determine values for scaling coefficients that, when utilized by the parasitic extraction tool to generate the parasitic netlists, allow differences between the parasitic netlists and the reference netlists to fall below threshold levels. The determination of the scaling coefficients is performed by iteratively adjusting the values of the scaling coefficients based on differences between the reference netlists and the parasitic netlists generated with the scaling coefficients having the adjusted values. The computing system can utilize the adjusted scaling coefficients to generate parasitic netlists having differences with the reference netlists that fall below threshold levels of the test cases.
