MyHDL FPGA Tutorial I (LED Strobe)
Last updated 05-Nov-2015Introduction From many perspectives the latest FPGA offerings from 'X' and 'A' are large devices - mucho programmable logic resources. Even the devices that one can get for sub \$10 are relatively large. ...
Using GHDL for interactive simulation under Linux
The opensource and free VHDL simulator 'GHDL' has been out for many years, but like many other opensource tools, it has caught limited attention from the industry. I can hear you thinking: 'If it doesn't cost money, it can't be worth it'. Well, I...
VHDL tutorial - A practical example - part 3 - VHDL testbench
In part 1 of this series we focused on the hardware design, including some of the VHDL definitions of the I/O characteristics of the CPLD part. In part 2, we described the VHDL logic of the CPLD for this design. In part...
Verilog vs VHDL
Introduction Verilog and VHDL are two industry standard Hardware Description Languages (HDL) that are used in writing programs for electronic integrated circuits (ICs) i.e., ASIC and FPGA. Many system designers face this issue: which HDL...
Developing FPGA-DSP IP with Python
This blog post was previously titled MyHDL ASIC Proven (How is this related to FPGAs?) but the blog post has been updated and mainly discusses developing FPGA-DSP IP with Python / MyHDL. The original content is still present but the post has...
New Design - Finally!
For those of you who are familiar with my work, you already know that FPGARelated.com is not the only engineering web site that I publish. I also publish DSPRelated.com and EmbeddedRelated.com. Those two web sites have been on a new design for...
VHDL tutorial - part 2 - Testbench
[quicklinks]In an earlier article I walked through the VHDL coding of a simple design. In this article I will continue the process and create a test bench module to test the earlier design. The Xilinx ISE environment makes it pretty easy to start...
VHDL tutorial
When I was first introduced to "Programmable Logic" several years ago, it was an answer to many of the challenges that I was struggling with. Though the parts were primitive by today's standards (simple PALs verses FPGA), they were an extremely...
Summer of gateware is coming (again)
How time flies! I swear my last post was a summary of the 2015 summer of gateware. This year (2016) MyHDL is participating in the Google summer of code again, for the second year, continuing as a sub-org of the Python...

How FPGAs work, and why you'll buy one
Today, pretty much everyone has a CPU, a DSP and a GPU, buried somewhere in their PC, phone, car, etc. Most don't know or care that they bought any of these, but they did. Will everyone, at some future point, also buy an FPGA? The market size...
MyHDL FPGA Tutorial II (Audio Echo)
Introduction This tutorial will walk through an audio echo that can be implemented on an FPGA development board. This tutorial is quite a bit more involved than the previous MyHDL FPGA tutorial. This project will require an...

BGA and QFP at Home 1 - A Practical Guide.
It is almost universally accepted by the hobbyists that you can't work with high-density packages at home. That is entirely incorrect. I've been assembling and reflowing BGA circuit boards at home for a few years now. BGAs and...
