DECUS Heritage
Version: 3.0, May 1987
Submitted By: Digital Equipment Corporation
Operating System: VAX/VMS V4.3
Source Language: C
Keywords: Circuit Simulation, Engineering Applications, Simulations
Software Requirements: C Compiler
Memory Requirements: 3MB
Notes: This program was developed by the Computer-Aided Design Group, Department of Electrical Engineering and Computer Sciences, University of California- Berkeley.
Changes & Improvements: The input language has changed slightly to remove certain unnecessary punctuation, such as colons and commas. The specification for subcircuits allows parameters to be passed into a subcircuit along with the node names. The ITA algorithm has a variable time-step control and can handle tightly-coupled analog circuit blocks more effectively. The MOS models have been upgraded to include MOS level 3 [Vla81] of SPICE2 and the Yang-Chatterjee MOS model [Yan83].
Restrictions: Operating system VMS V4.3 or later is required. The C compiler is needed for compilation.
Abstract: SPLICE3 [Sa186] is a new mixed-mode simulation program [New78, Kle84] which performs fast and accurate transient analysis of Metal-Oxide-Semiconductor (MOS) integrated circuits. The program uses a mixture of direct methods, similar to the techniques used in the SPICE2 [Nag75] program, and a modified version of "Iterated Timing Analysis" (ITA) [Sal83]. This combination can greatly improve the computational efficiency of circuit simulation for MOS Digital circuits by exploiting their loose coupling and relative inactivity, and still efficiently solve tightly coupled analog circuits by switching automatically to direct methods when appropriate. At the present time, only the electrical analysis is available to the user. The logic analysis and mixed-mode aspects of the program are still under development at the present time. The electrical analysis in SPLICE3 produces results which are as accurate as SPICE2 for both analog and Digital MOS integrated circuits, but uses less than 10% of the computer time for large circuits.
