Nonlinear approach to scaling circuit behaviors for electronic design automation

摘要

Circuit behaviors are scaled to different operating conditions by using a generalized nonlinear model. Nonlinear transforms are applied to the operating conditions and/or to the circuit behaviors contained in a library set. The transformed quantities have a more linear relationship between them. Parameters for the linear relationship are estimated based on the data and operating conditions in the library set. These parameters and nonlinear transforms can then be used to scale circuit behaviors to operating points not contained in the library set.
