Dedicated Analog Circuit Simulation Programs

This paper has as a main purpose the presentation of three dedicated programs for analog circuit simulation, developed by the research team at University Politehnica of Bucharest (UPB): Circuit Symbolic Analysis Program (CSAP), Transfer Function Symbolic Generation (TFSYG), and SYmbolic State Equation Generation (SYSEG). These dedicated programs present a series of advantages as compared to the commercial software (e.g. SPICE). The article exposes the steps for using the afore-mentioned programs and how to analyze the obtained results. Examples of various circuit structures are given for each type of analysis. Some examples are analyzed in parallel with the SPICE program to check the accuracy of the obtained results.
