Patent ID: 7171346

Claim:
A mismatch modeling tool comprising: a software implemented transistor mismatch model (“SITMM”); at least one editable mismatch model data library comprising process parameter variables accessed by said SITMM; a circuit simulation library and program data output accessed by said SITMM; and a graphical interface to said SITMM, the graphical interface having: (a) a plurality of string-of-data input parameter fields to provide a plurality of input parameter data strings to the SITMM for generating results for at least one mismatch parameter over the plurality of input parameter data strings, wherein each of the string-of-data input parameter fields accepts a delimited list of values for each geometry, bias, and temperature condition parameter, and (b) a plurality of range-of-data input parameter fields to provide a plurality of input parameter ranges of data to the SITMM for generating results for at least one mismatch parameter over the plurality of input parameter ranges of data, wherein the mismatch modeling tool is configured for utilization via a web interface.
