Digital outputs can either go ON or OFF. Analog signals, on the other side, can smoothly assume multiple values in a range. There is a technique that emulates analog behavior with a digital output. That technique is PWM, namely, Pulse Width Modulation. It can be implemented as pulses with varying ‘high’ and ‘low’… Read More

Pseudo random generator tutorial in VHDL (Part 3/3)
On the first two chapters of this Tutorial we started with a simple LFSR module and added a test bench. Then, on chapters three and four we upgraded our module with some features and learned to export the test bench data to files.

Pseudo random generator tutorial in VHDL (Part 2/3)
In the first part of this tutorialwe started with a simple implementation of an LFSR block (Chapter 1) and its test bench (Chapter 2). Let’s make our code look a bit more professional.

Pseudo random generator tutorial in VHDL (Part 1/3)
In this tutorial we will see how to design a VHDL block. We will start with a very simple block and we will gradually add features to it. We will also simulate it and test its output with Matlab. Over the process we will see:
