Method of mixed-mode circuit and device simulation

The paper presents the method of mixed-mode circuit and device simulationbased on the two-level Newton algorithm, and successfully developed a mixed-mode simulator by incorporating the device simulator PISCES into the circuit simulator SPICE3. Themixed-mode simulator has avoided the complex process of model building by directly applying device simulator as the device model in circuit simulator. A numerical device model builtin the mixed simulator is general to any devices in the device simulator, and can easily adaptto the updating of new devices. To reduce the overall run time of mixed simulation, a parallel processing mode is made in the networked workstation environment through a remote executing function of UNIX system. The mixed-mode simulator is a powerful simulation tool fordeveloping new devices and circuits.
