PyOPUS is a Python based platform for very sophisticated circuit optimization and simulation automation. The use of the Python library with the simulator requires a previous SPICE OPUS installation, then refer to the relative tutorial before proceeding. Below we show how to install PyOPUS on windows 7 (64 bit). All …Read More »

SPICE OPUS is an acronym for SPICE engine for OPtimization UtilitieS. It’ s a recompilation of the original Berkeley’s source code for Windows 95/98/NT and Linux operating systems with Georgia Tech Research Institute’s XSPICE mixed-mode simulator. You can simulate analog, digital, and analog+digital circuits using SPICE OPUS. It’s available for both …Read More »
