A Python interface for SPICE-based simulations

This paper introduces a programming interface for integrated CMOS circuit design. It connects the SPICE netlist level to an easy to use programming language: Python [1]. After classifying the context of this tool the fundamental application for parametric circuit simulation and signal processing is shown. This is done at the example of a parameterizable netlist for an inverter. Further on, calculations for a single MOS-device are shown. Normally required input parameters for SPICE can be set to be calculated in dependence of specified normally calculated output parameters. It is also shown how to deal with a two-dimensional search of input parameters.
