It's been a while since my last post, and although there has been some interesting work on more example designs (which just got sent to fab 🎉) that'll be another post for another day, hopefully with some fun videos. But today, we revisit an old friend: refactoring the compiler. Again. IntelliJ...

Can you spot the difference from last week's board design (I mean, aside from the duck 🦆 moving)? Right above the LEDs, instead of 4 resistors, there's now 2 4-pack resistors (RN1 and RN2). Up to this point, the board design HDL followed a pretty strict hierarchy block design structure. Hierar...

Last week's work was adding array-to-array connects, but array-valued expressions (eg, [1, 2, 3]) are helpful in parameterizing variable-sized devices, like a n-ported resistive divider. So that's what this week was, but as with everything else, easier said than done. The main issue is trying to...

Continuing off the implementation of port arrays for microcontroller IOs in the last post is support for array-to-array connections. While prior we could only connect ports to arrays, now, we can do something like this: The updated RGB LED definition defines its IOs as an array of 3 digital in...

Finally, payoff for a feature that's been in low-level development for over a year, and in heavy development for the past few weeks! Port arrays are now advanced enough to implement an abstract microcontroller class, and the end-to-end demo is apparent from the source-measure unit example layout: ...

Weekly WIPs (work in progress) are shorter posts that describe projects or features that are still being worked on, as opposed to fuller posts looking at completed work. Most features take weeks to build, so these are smaller intermediate progress reports, but hopefully will still be interesting! ...

We always like to see when we can remove more lines of code than we add. The refactor mentioned in the blog post two weeks ago is finally done and merged, and in general refactoring is wrapping up. Hopefully new feature development (port arrays, then multipack devices) will start next week. A...
