SPICE OPUS analog circuit simulator

About
SPICE OPUS is based on the Berkeley SPICE3f4 analog circuit simulator. The original simulator was cleaned up, many device models were added, the convergence algorithms were improved, a terminal window and plotting utilities were reimplemented using Qt. SPICE OPUS was developed with circuit optimization in mind. The optimization algorithms were implemented into teh simulator which makes them particularly fast as no time is wasted with restarting the simulator for every candidate circuit. A byproduct of this developement was a cleaned-up and memory-leak free NUTMEG scripting language which is built into SPICE OPUS.
