Advanced circuit and device modeling with verilog-A

The hardware description language Verilog-A is today de facto the standard language for compact circuit and device modeling and it is implemented in almost all major commercial SPICE-like circuit simulators. The goal of this paper is to present the principles and techniques for implementation of various circuit and device modeling constructs in Verilog-A. Practical examples include a mixed lumped element and network function based modeling of a bipolar transistor as well as a physical, PDE based, modeling of a PIN diode
