MyHDL Resources

If you want to dive into MyHDL (digital hardware description in Python) there are many resources available.  Below is a list of MyHDL resources, including some of the past blogs here on fpgarelated.

The MyHDL manual is a great (probably the best) place to get started.

• MyHDL Manual

The manual is an in-depth introduction to MyHDL.  The concepts are well explained and there are examples to test while working through the manual.

The creator of MyHDL, Jan Decaluwe, has authored numerous -very informative- pieces on MyHDL and hardware description languages.  Below is a subset of Jan's posts.

• Designing Digital Hardware with Python (presentation)
• These Ints are Made for Countin'
• Wasting real time in zero time
• Pitfalls for circuit girl
• The Case for a Better HDL
• MyHDL - Based Design of a Digital Macro

NOTE: the following set of links are articles that were on the "All Programmable Planet" (APP) site.  In late 2013 the APP site was disbanned.  The following set of links are redirected to the same spot (an article explaining what happened to APP - well kinda).  These links will remain here in hope that the content will be restored at some point in the future.

• MyHDL: Why Do We Need Signal Assignments (updated valid link)
• MyHDL: Why HDL designers should learn Python (updated valid link)
• MyHDL: Reference Model for Cellular Automata (broken link)
• MyHDL: Modeling for Synthesis (broken link)
• MyHDL: Thinking Software at the RTL Level (updated valid link)

If you read through all of Jan's post listed above you will learn quite a bit about HDLs and MyHDL!

• FPGA design with Python and MyHDL (presentation)
• Enhancing hardware design flows with MyHDL (presentation)
• Why you should be using Python/MyHDL as your HDL (presentation)
• RTL design in Python: porting the mMIPS [ppt] (presentation)

A couple YouTube presentations.

• Jan Decaluwe's PyConWT Key Note
• PyCon Argintina Presentation (spanish)
• PyOhio Introduction to Digital Hardware Design and MyHDL

The links below are some design examples using MyHDL, most of these are small projects/examples that can be tackled by someone getting started with MyHDL.

• Simple FPGA LED
• Audio Echo on FPGA
• Developing FPGA-DSP IP with MyHDL
• Delta-Sigma Digital-to-Analog Core
• FT245R USB-FPGA Interface
• MyHDL Fixed-Point, fixbv MEP
• Continuous Sine Waveform Generator
• Sine Wave Generator using Sigma Delta DAC

The previous list is a small taste of the projects that can be found on the web.  Googling will uncover many more MyHDL projects.

The last set of links are some examples available in the online repositories Bitbucket and Github.  

• Portable Software Defined Radio (SDR)
• Ovenbird automate Vivado

  • 10G Ethernet
  • JPEGEnc
  • GEMAC
  • AXI Test Interface
• ZPU with MyHDL (an old template / start)
• Nintendo Entertainment System (github)

In addition, there are many examples and projects posted on the MyHDL website in the by example and user pages.

If others know good sources and/or projects and examples feel free to post in the comments section.
