The following is a list of new features and fixes from the previous release of Spice3, 3f. MOS3 discontinuity fix "kappa". Added a new JFET fitting parameter. Minor initial conditions fix.

Rewritten or fixed "show" and "trace" commands. New interactive commands "showmod" and "alter". Minor bug-fixes to the Pole-Zero analysis. Miscellaneous bug fixes in the front end.

Note that the 'gcc' C compiler was used successfully to compile Spice3f. Due to the heavy use of floating point math operations, Spice3 on the PC requires a math co-processor.

The links in this section are to obsolete versions of MacSpice that are of mainly historical interest but may also be useful to a small number of users with special circumstances. MacSpice 2. This obsolete version is provided for people who need to run on OS 8. This obsolete version is provided for people who are using OS 8. MacSpice simulates and analyses electronic circuits that can range in complexity from a single resistor to an integrated circuit comprising tens-of-thousands of devices.

It has users who range in experience from novices to retired integrated circuit designers. It is used at various universities internationally for research and teaching. MacSpice 3. It is compatible with, Berkeley Spice 3f5 but 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 3f5 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.

You can still try this if you want, to get an idea of how much work we need to do! Just enter "msc51" at the DOS prompt and wait a minute or two as thousands of messages fly by If you look through the source, you will see that in every folder there is a "msc Apparently, MS has changed some of the syntax of the command line compiler since then, so we need to make a lot of changes.

You will need to check this file after every compile attempt to see what went wrong Use "Notepad" or "Wordpad" to view this file.

OUT" file with kB of error messages. The first messages deal with a problem in port. If you just double-click on it from Explorer, Visual Studio should open the file for editing. You must also do this in subfolders "..

Now for some real work For big files, I used the "replace" feature of Notepad to make this go a little faster At this point, we're half done so it's a good time to show some progress. This will create the library files "..
