Verilog is a Hardware Description Language (HDL) used to describe a digital system: for example, a network switch, a microprocessor or a memory or a simple flip-flop. This just means that, by using a HDL, one can describe any hardware at any level.
This manual is the reference needed when working with special circuit analyses in PSpice A/D. It covers detailed command descriptions, definitions of start-up option, and a list of supported devices in the digital and analog device libraries.
