  • Apparatus and methods for modeling and simulating the effect of mismatch in design flows of integrated circuits
    Patent number: 6560755
    Abstract: An exemplary method for simulating the effect of mismatch in design flows comprises receiving measured data, receiving an original model, extracting a mismatch model based on the measured data and the original model, attaching the mismatch model to the netlist to obtain a modified netlist, and simulating an effect of mismatch based on the modified netlist. In one embodiment, the extracting of a mismatch model includes selecting a set of model parameters, generating a distribution of mismatch values for each of the model parameters, extracting a set of linking coefficients based on said mismatch values, and extracting said mismatch model based on said set of linking coefficients.
