myhdlpeek

A module that lets you monitor signals in a MyHDL or nMigen 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 implements a Peeker object that monitors a signal and records the time and value when it changes. Just add multiple 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 much more.

[This Jupyter notebook] shows how to use myhdlpeek.

Features

• Captures timing traces of signals in a MyHDL/nMigen 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.
• Tabular output in Jupyter and console.
• Trigger expressions allow the display of a selected portion of traces.
