Previously I designed a simple configurable countdown Timer with asynchronous reset, enable and limit. Now I will add a pre-scaler to the Timer. What exactly is a pre-scaler? You can think of the pre-scaler as an integer value that scales (or divides) the timer clock signal down to a lower frequency. Why Do We Need […]

This time I am going to create a configurable timer circuit with both an enable and a settable start value. You may recall that we’ve previously created counter circuits. For some examples see Creating a Configurable counter Circuit and Designing a Simple 4-bit Counter Circuit. Timers and counters are close related and very similar. It

In this post I am going to look at test bench data files. As circuits become more complex there will be more test cases for inputs. It will become increasingly tedious to write code for each of the possible test cases for inputs. So I want to see if I can simply testing before then.
