WireViz VS glasgow

If you don't mind my asking, what aspects of "acceptable layout" is usually the first to get busted?

I'm extremely excited about using WireViz[1] to automate wiring harness diagram creation, and if I can, I'd like to know the speedbumps before I hit them. I'm thinkin generous linking between diagrams will be one path.

Like WireViz?

WireViz is nice for generating manufacturing files for wiring looms, but you might want to use something else for descriptive documentation diagrams

WireViz, Easily document cables and wiring harnesses WireViz is a little tool very handy to document your cabling and get beautiful visual from it.

I found that wireviz does have multicolour support, dashed and stripes but maybe not the angled one we'd need for earth lead in Australia (iec also). Diagrammatically it should look like a barbers pole. yellow and green

This post is so timely!

Does anybody in this thread have details about the H-UDI proprietary SH4 JTAG extensions? Context here:

Hmm. A followup question: are there any cheats/hacks that would make it possible (if painful) to for example explore the world of USB3, PCIe, or Linux on low-end-ish ARM (eg https://www.thirtythreeforty.net/posts/2019/12/my-business-c..., based on the 533MHz https://linux-sunxi.org/F1C100s), without needing to buy equipment in the mid-4-figure/low-5-figure range, if I were able to substitute a statistically larger-than-average amount of free time (and discipline)?

For example, I learned about https://github.com/GlasgowEmbedded/glasgow recently, a bit of a niche kitchen sink that uses https://github.com/nmigen/nmigen/ to lower a domain-specific subset of Python 3 (https://nmigen.info/nmigen/latest/lang.html) into Verilog which then runs on the Glasgow board's iCE40HX8K. The project basically makes it easier to use cheap FPGAs for rapid iteration. (The README makes a point that the synthesis is sufficiently fast that caching isn't needed.)

In certain extremely specific situations where circumstances align perfectly (caveat emptor), devices like this can sometimes present a temporary escape to the inevitable process of acquiring one's first second-hand high-end oscilloscope (fingers-crossed the expensive bits still have a few years left in them). To some extent they may also commoditize the exploration of very high-speed interfaces, which are rapidly becoming a commonplace principal of computers (eg, having 10Gbps everywhere when USB3.1 hits market saturation will be interesting) faster than test and analysis kit can keep up (eg to do proper hardware security analysis work). The Glasgow is perhaps not quite an answer to that entire statement, but maybe represents beginning steps in that sort of direction.

So, to reiterate - it's probably an unhelpfully broad question, and I'm still learning about the field so haven't quite got the preciseness I want yet, but I'm curious what gadgetry, techniques, etc would perhaps allow someone to "hack it" and dive into this stuff on a shoestring budget? :)
