In the previous tutorial, we learned how to use a For-Loop to iterate over an integer range. But what if we want a more detailed control of the loop than just a fixed integer range? We can use a While-Loop for this. The While-Loop will continue to iterate over the enclosed code ...
We can utilize this clocking hardware to generate clocks for use in our HDL designs running on PL section of Zynq. Rest of this article will attempt to explain how to do this practically. Here is what we are going to do: We will take a Verilog design which requires a 100MHz clock to ...
In this article, we will learn how we can use Verilog to implement a testbench to check for errors or inefficiencies. We’ll first understand all the code elements necessary to implement atestbench in Verilog. Then we will implement these elements in a stepwise fashion to truly understand the...

You will need to write a testbench for stimulus. We don't usually offer the code in the forum, but here is some example you can try out: module testbench; reg [10:0] input_signal; integer i; real pi = 3.14159; real sin_value; initial begin for (i = ...
The Counter stimulator can be applied to VHDL signals of one-dimensional array types and integer types and Verilog integer registers and vectors. It produces a sequence of values that represent consecutive states of a counter. You can set the count step and direction, the time interval between ...
43698 - 13.2 EDK - How to link user VHDL/Verilog library in XPS? Description I have created AXI peripherals using XPS. There are constants I need to extract from the peripherals, such as bit definitions. I created a user VHDL library in ISE, and added the 'library' and 'use' directives...
Re: How to add time delay in verilog code « Reply #1 on: June 06, 2016, 10:31:30 pm » No, there's no better way. A digital, synchronous design uses counters to create delay. You can simply count up an integer or reg and act when reached whatever delay you need. Logged ...
