Compact Model Library for Circuit Simulation

12.1  Introduction

In Chapters 4 through 11, we have discussed compact model formulation for different VLSI (very-large-scale-integrated) devices. In this chapter a brief overview of the generation of compact model library for circuit simulation and compact model usage in circuit CAD (computer-aided design) is provided. A typical CMOS (complementary metal-oxide-semiconductor) technology and Berkeley Short Channel IGFET Model, version 4 (BSIM4) compact MOSFET (metal-oxide-semiconductor field-effect transistor) model are used to illustrate the methodology to build a compact model library for HSPICE (see Chapter 1) circuit CAD [1,2]. Note that the circuit CAD tools and the device models are continuously ...
