10Project Based on Verilog HDLs

This chapter includes VLSI projects based on digital circuit design using Verilog programming and functional verification with a truth table on Xilinx tool [1–2]. The project includes all four levels of abstraction of Verilog from the switch-level to behavioral-level model. Each project gives a basic description of design including truth table and design verification results.

Xilinx ISE is one of the useful simulators that uses Verilog/VHDL languages to design and implement any digital logic virtually. Figures 10.1–10.4 show how the Xilinx ISE simulator interfaces to create a project, select the Verilog module, text editor, and waveform window, respectively.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
