myhdlpeek 0.0.1

Peek at signals in a MyHDL digital system simulation.

A module that lets you monitor signals in a MyHDL digital system simulation and display them as waveforms in a Jupyter notebook. Make changes to your digital design and see the results reflected immediately in the waveforms of your notebook!

myhdlpeek uses a Peeker objects that monitor signals and records the time and value when they change. Just add the Peekers where you want to monitor something (even at sub-levels of a hierarchical design) and then view the collected timing waveforms with a single command. You can also select which signals are shown, set the beginning and ending times of the display, and set other options.

Below are some examples of Jupyter notebooks using myhdlpeek. Unfortunately, Github doesn’t render the waveform displays so you’ll have to download and run the notebooks locally to see what myhdlpeek can do.

• Simple multiplexer.

• Hierarchical adder.

• Other Peeker options.

• Free software: MIT license

• Documentation: http://xesscorp.github.io/myhdlpeek

Features

• Captures timing traces of signals in a MyHDL digital design.

• Works at the top-level and sub-levels of a hierarchical design.

• All signals or a selected subset can be displayed.

• The beginning and ending points of the waveform display can be set.

• Timing marks can be turned on or off.

• Titles and captions are supported.
