### Courses and Presentations

**A Quick Circuit Simulator Primer**

Those who write compact models for use in circuit simulation need a basic understanding of what goes on inside a circuit simulator. This presentation is a short introduction for beginners. It briefly covers how circuit equations (so-called Differential Algebraic Equations, DAEs) are built up and how they are solved to find the circuits' steady state solutions (by Newton Raphson iteration). It also discusses how circuits are defined (in netlist format), how different kinds of analyses (DC, AC, and TRAN) are run, and how results are displayed and interpreted.

**Introduction to Compact Models and Circuit Simulation**

**Purdue University (2013)**

Taught by Tianshi Wang, and Jaijeet Roychowdhury

Selected topics: compact model, basic circuit simulation, flows for developing compact models, NEEDS-SPICE

**UC Berkeley SPICE3 Tutorial**

By Tien-Cheng Bau and Samiha Mourad

SPICE is a general-purpose circuit simulation program for nonlinear dc, nonlinear transient, and linear ac analyses. Circuits may contain passive components (resistors, capacitors, inductors), active devices (transistors and diodes), and independent voltage and current source…, etc. In this tutorial, we will illustrate the use of the simulator with a CMOS inverter.
