1.0
Nearly a year after 0.0.30, today marks the release of SKiDL version 1.0.0. But why assign such an exalted milestone to this release given the relative paucity of new features, most of them mundane (with the possible exception of automatic...
Automatic Schematic!
Everybody wants ERC. Everybody hates ERC. Electrical rules checking (ERC) looks for errors in how your circuit is constructed. It’s like running lint, but for hardware. And as with lint, you get a whole bunch of warnings that don’t matter...
Customized ERC!

Good Things Come In Packages!
Up to now, SKiDL supported hierarchy by applying the @subcircuit decorator to a Python function: @subcircuit def analog_average(in1, in2, avg): """Output the average of the two inputs.""" # Create two 1K resistors. r1, r2 = 2 * Part('Device', 'R', value='1K',...
New SKiDL Forum!
I created a Discourse forum for SKiDL. There, you can ask questions about SKiDL and post about projects you’re doing with it. This will probably be a more convenient channel for such things rather than opening issues on the SKiDL...
Version 0.0.30 Released!
I’m releasing version 0.0.30 of SKiDL today! It has some new features I’m excited about: A new @package decorator to make subcircuits act like Parts. A new tee() function for creating T-junctions in networks. Custom ERCs can now be added...
xspice capability
Somebody asked about using XSPICE components in SPICE simulations with SKiDL. That wasn’t possible since PySpice didn’t really support these when I built the interface. So I added XSPICE parts to the SKiDL SPICE interface and released it as SKiDL...
Version 0.0.28 Released!
Well, that didn’t last long. I released version 0.0.27 of SKiDL yesterday, but I didn’t like having the zyc utility bundled in there because that pulls in wxpython as a requirement. That’s likely to cause problems for some people when...
Version 0.0.27 Released!
It’s been almost eleven months since I released a new version of SKiDL (not counting updates to the Github repo). So here’s a new one: version 0.0.27. You can install it using pip just like all the other releases. Check...
The Worst Part of SKiDL
I created SKiDL to replace the manual tedium of drawing schematics with the advantages of modern programming languages: iteration, abstraction, hierarchy, and modularization. But one thing always stood out as a problem: Parts. Here’s a snippet of SKiDL code to...
