a few cool things

mi-sugar is an excellent SPICE/Gnucap interface for OS X. The author stopped distributing the code in mid-2006, and apparently every single download site only has “external mirrors” pointing to the author’s nonexistent binary. I finally found a copy, so I’m mirroring it here since it’s considered abandonware.

Details:

The circuit simulation engines of MI-SUGAR were the free tools SPICE and Gnucap. The user could create analog circuits using the schematic entry tool or the netlist editor, then run the simulation and, finally, inspect the results in the graph plotter. Users could also build their own library of circuit elements.

Note: here is where I found my copy (no guarantees on how long this will stay up)
