Stixu: VLSI Stick Diagrammer

I got two signatures at ASYNC 2025 - one in a physical book I just happened to be carrying (I didn't realize Dr. Sutherland was in the community) and another in my e-reader copy of the entry point of many younger people to the field.

Stixu now has a demo mode that pre-loads a diagram:

stixu.io?demo=1

It also now has features to export to IRSIM (recommended) or Verilog (might need some improvement, experimental) for event-based simulation.

I regularly get these kinds of industrial espionage offers.

Just contact PR if you want to do this legitimately.

This also has nothing to do with it. Heaven forbid I accidentally hit tab while writing code after Copilot "helpfully" suggests new bugs to introduce.

Thanks Visual Studio and Copilot, this has *nothing whatsoever* to do with the code I'm committing

Copilot (it's free since I have a student Github account) is a hindrance after the boilerplate is done, and in cases like this openly hostile

Is this what the grifters call "vibe coding"?

A snippet from Numerical Recipes: The Art of Scientific Computing (FORTRAN Version)

I've held onto this book since a professor disposed of it a decade ago. The language is dated, but the algorithms are timeless

How about sequential circuits? State-dependent values appear as U (can be Z, 0, or 1), L (can be Z or 0), and H (can be Z or 1).

For example, is a MUTEX (mutual exclusion) element, common in asynchronous circuits.

What happens if you have a short-circuit? Exactly what you would hope - you get an invalid X in the truth table.

What if the output is floating? You get a Z, as expected.

And of course, a simple inverter

Let's look at a few basic circuits...

Here are NAND2 and AND2

The default colorblind-accessible color scheme may not be the most familiar to users, but no worries! The "Sorcery" color scheme in the menu should make #MagicVLSI users feel at home.

Stixu.io is a free #CMOS #StickDiagramming tool.

It is useful for undergraduate students working on digital chip layout assignments and can serve academics as an intuitive tool to illustrate, analyze & validate #VLSI circuit topologies 🧵

This excerpt from _Speech and Language Processing_ (third edition draft) by @jurafsky.bsky.social and Dr. James H. Martin answers a question I've had since I first learned about dynamic programming over a decade ago, and is an example of how history often rhymes.
