Arrays, Dynamic Arrays, Queues: One List to Rule them All
[](/legacy-img/splash-13.png) Randomizable lists are, of course, very important in modeling more-complex stimulus, and I've been working to support these within PyVSC recently. Thus far, PyVSC has attempted to stay as close as possible to both the feature…
Python Verification Stimulus and Coverage: Constraints
[](/legacy-img/splashconstraints.png) Over the past few blog posts, we've looked at: - [The fundamentals of modeling stimulus and functional coverage in Python](/blog/modeling-random-stimulus-and-functional-coverage-in-python/) - [Modeling verificati…
Python Verification: Working with Coverage Data
[](/legacy-img/splash-4.png) Before jumping into this week's post, I wanted to offer a bit of an apology to my readers. I recently realized that, despite being a Google property, Blogger only notifies authors of comments for moderation if the author h…
Python Verification Stimulus and Coverage: Functional Coverage
[](/legacy-img/pyvsccoverage.png) In my last two posts ([here](/blog/modeling-random-stimulus-and-functional-coverage-in-python/) and [here](/blog/python-verification-stimulus-and-coverage-data-types/)), I've been talking about modeling random stimulus, …
Python Verification Stimulus and Coverage: Data Types
[](/legacy-img/ModelingRandomStimulusSplash-2.png) In my last post, [Modeling Random Stimulus and Functional Coverage in Python](/blog/modeling-random-stimulus-and-functional-coverage-in-python/), I introduced a Python library for modeling random vari…
Modeling Random Stimulus and Functional Coverage in Python
[](/legacy-img/ModelingRandomStimulusSplash.png) If you've been following the blog over the last year, you've probably noticed that I've spent quite a bit of time over the last year learning and using Python. For several reasons, it's become my new favor…
Selectively Muting your BFMs to Speed up Simulation
[](/legacy-img/splash-7.png) Have you ever had the misfortune to be on the CC list for a "lively" email discussion where you're a stakeholder but only case about the conclusion? You can't simply ignore the traffic, because you do care about the conclusio…
2019 - The "Nights and Weekends Projects" Year in Review
[](/legacy-img/splash-16.png) It's almost the end of 2019, and I've been thinking back over the year as well as thinking ahead to 2020. In past years, I've often evaluated my "nights and weekends" projects using the same metrics I'm evaluated on at work:…
Writing a Task-Based Cocotb BFM
[](/legacy-img/splash-6.png) Background The purpose of a Bus Functional Model (BFM) is to enable interacting with a design via a given protocol at a higher level of abstraction than the signal-level protocol, while knowing the bare minimum about the…
Adding Task-Based Bus Functional Models to Cocotb
[](/legacy-img/splash-12.png) Getting a project started -- even to a certain level of completeness -- is often pretty simple. A couple weekends of hacking often results in pretty good progress and results. Finishing things up, in contrast, is often…
