References: Verilog

You might remember some of this from CPE280 or CPE282, but we're not betting on that. Here are the basics for using Verilog.

It is worth noting that the particular Verilog we will use is Icarus Verilog, which is an open-source toolchain that is very faithful to the Verilog standard. Tools from Xilinx, for example, are not as full implementations of Verilog, so some things we discuss here may be unsupported in whatever toolchain you would use outside of this course. For example, the Xilinx tools are known to have problems with recursive modules.

Also note that the textbook does not discuss Verilog. The materials linked here are your primary reference.

• Icarus Verilog (iverilog and vvp) is the primary tool we'll be using for compiling and simulating Verilog code. It is actually part of gEDA. Note that you can install it on Ubuntu Linux systems by simply selecting it in the Software Center or Synaptic -- it's a standard part of the Ubuntu distribution, as well as having been ported to Windows, etc.
• Icarus Verilog Simulator CGI Interface created by Professor Dietz and used for Verilog code throughout this course
• EDA playground is an alternative WWW interface for running Icarus Verilog... and various other tools including some commercial simulators. Requires Log In for use, but registration is free.
• ASIC World has a multitude of really nicely prepared materials showing how to use Verilog
