PyOPUS documentation - table of contents
PyOPUS is a library for simulation-based optimization of arbitrary systems. It was developed with circuit optimization in mind. The library is the basis for the PyOPUS GUI that provides a simple way for setting up design automation tasks. In the GUI you can also view the the results and plot the waveforms generated by the simulator.
