 MacSpice 3f5 - 2.10.03 Spice 3 electronic circuit simulation (File Size: 2.7M) Current Version: 2.10.03 Release Date: 2007-12-08 License: Freeware Broken Link? Newer Version? Tell us! Product Description: Circuit simulation is a way of building and testing virtual models of electronic devices. It is usually cheaper and quicker to simulate a design than to build a prototype. MacSpice, like most circuit simulators, requires a text-file description of the circuit as input. This 'netlist' is a list of components and the nodes they connect to. Users may prepare netlists with a text editor, or derive them from a circuit diagram using a third-party schematic-capture application. MacSpice then builds a numerical model of the circuit and analyses this. A command interpreter (shell) is used to specify the types of analyses that are required and how the results should be processed, saved or displayed. The high quality of the MacSpice command interpreter makes the automation of tasks straightforward. MacSpice has native support for both PowerPC and Intel architecture Apple Macintosh computers. It is derived from, and compatible with, Berkeley Spice 3f5. MacSpice incorporates many improvements to Spice 3f5 - from simple bug-fixes to entirely new commands, algorithms and solution strategies. For example: the memory leaks that affected Spice 3f4 have been cured; new algorithms have been developed to facilitate the simulation of large circuits, and to reduce simulation time; MacSpice provides a robust multi-parameter optimizer and facilities for inter-process communication with other applications. What's new in this version: Enhancements: * align self-update system with Sparkle 1.5 code; * 'Del' key now deletes forward from the insertion point, as opposed to the backspace key which deletes back from the insertion point. Bugs fixed: * intermittent crash on MacIntel when applescript command has a syntax error; * memory leak and hypothetical crash in auto-update code; * crash if CpLines device has malformed definition; * garbage (instead of a line number) in error report. Operating System Requirements: This product is designed to run on the following operating systems: * Mac OS X 10.4 Intel * Mac OS X 10.4 PPC Additional Requirements: * Mac OS X 10.4 or higher (versions for Mac OS X 10.1 - 10.3.9 and Mac OS 8.6 - 9.2.2 available at alternate link) Screenshots:
