Spicedim - a CAD tool for supporting circuit sizing of analog CMOS circuits

This paper introduces Spicedim, a graphical programming interface for integrated CMOS circuit design. It connects the SPICE netlist level to an easy to use programming language, both combined in a graphical development environment. 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 a current mirror. Further on, Spicedim supports calculations at single MOS-device for a device by device circuit sizing concept. Normally required input parameters for SPICE can be set to be calculated in dependence of specified normally calculated output parameters.
