Spice 3f4

Spice is an analog circuit simulation program. Version 1.7.6 is based on the University of California at Berkeley Spice version 3f4 . Circuit descriptions are entered as a Spice netlist with any text editor and then analyzed with the Spice program. The program can perform AC, DC, Transient, Pole-Zero, Sensitivity, Transfer, Noise and Distortion analysis. Commands are entered into a text based command shell [O.K., it is not very Macintosh like but it preserves the original flavor and power] that allows both graphical plotting to the screen and printing. This release contains bug fixes from version 1.5 including: - fixed heap bug that would modify some "defines" after use - fixed heap bug with "sens" analysis - fixed bug in "sens" printf() - fixed heap bug with "alter" command - fixed variable substitution problem - fixed heap bug with "disto" analysis - improved heap management (AC DEC 500 1 1MEG now works) - improved executation speed on PowerPC Two CPU versions are included. One for the 68K that requires an FPU, the other for the PowerPC. Both versions should work on any MacOS greater than System 7.1. This is a large program and large circuits can consume large amounts of RAM. The minimum RAM required is 1536K, although much more is recommended. This program may be freely redistributed on a not-for-profit basis as long as all references to the University of California at Berkeley remain intact. It also may be included on commercially available CD-ROM versions of the archives as long as only a nominal media fee is charged.
