Introduction
This chapter includes the following topics:
Product Overview
SPICE
SPICE is a general-purpose circuit simulator developed by the University of California at Berkeley. It is used for nonlinear DC, nonlinear transient, and linear AC analysis. Cadence does not sell the SPICE program but supplies a copy of this public Domain program and its manual free of charge when you purchase the interface.
HSPICE
HSPICE is a general-purpose circuit simulator from Synopsys, Inc. It has an extensive set of built-in device models, including models for small geometry MOSFETs and MESFETs. The program is compatible with SPICE and MSING input formats. Cadence supports a library of primitives and a full interface for HSPICE.
