Macromodeling for Mixed Signal Circuits
MetadataShow full item record
Macromodels of functional blocks of VLSI circuits are used to reduce the computational effort involved in the detailed simulation of general-purpose circuits. However the macromodeling approaches in the literature have considerable limitations both in the type of circuits that can be modeled or the functions that can be simulated. In this paper we propose a method to generate macromodels for any kind of circuit and any kind of function that needs to be simulated, without restrictions. Furthermore our approach has a superior convergence properties, compared to the previous results in the literature. Therefore our method can get optimal macromodels in reasonable time and the models are accurate enough to be used for general circuit simulation.
