i'm not 100% sure, but I /don't/ think that's what the output from a CMOS XOR should look like :v

lethalbit,
@lethalbit@chaos.social avatar

@azonenberg I was originally trying to model a pass-transistor based XOR as it's only 6 MOSFETS as opposed to the 12 of the normal impl, but uh, it's not wiggling right >.>

thank you to the person who bought me an e/h near-field probe set for my birthday, it just got here, and that was very nice of you 🥺

@lethalbit@chaos.social avatar

@azonenberg Yeah! it's the Tekbox set, i need to get a wideband amp likely as i don't recall if my DSA815 has a built-in pre-amp but yeah I look forward playing with them and then eventually using them for their intentional purpose

me talking to myself: "why doesn't this SMA to N type adapter not have any wrench flats on it :v"

gotta torque it down nice and tight ya know.

@North i'm more of a green loctite kinda girl, gotta make sure it gets to the interface so the dielectrics are nice and bonded together too :v

Still grumpy at the lack of IO pads on the efabless MPWs, i could really use like, 100 I/Os, a 144 pin WLCSP or BGA would be nice.

OpenGL is confusing, >.< I need someone to hand-hold me thru this on a first pass, my brain is too smol

What's an EBO? What is all this fancy mess with a pipeline and shaders?

I just want to draw rectangles T~T

hey electronics mutuals,

what parts organization and cataloging method do ya'll use?

My current method is just everything grouped by project in a bag, and then a box full of bags :v

I was looking at maybe a local inventree instance or smth but weh.

hey lazyweb, does anyone know of any grammar based fuzzers?

Like, I feed it a EBNF and it generates valid and invalid test cases?

look at them :pleading:

So, Annie has a bell on her collar, but like, she's still basically silent when walking around unless she runs around or jumps, she's managed to startle me by being a silent little gremlin despite the bell many times, lol.

I've updated my KiCad PDK symbol library and generation bits! Now they include a rough SPICE link so it's close to possible to use KiCad for SPICE sims w/ PDK cells~ https://github.com/lethalbit/kicad-pdk-libs

Ugh, why do people accept awful tooling for FOSS EDA,

Or maybe i'm just a grump,

Either way OpenRAM is just, ugh, not built well >.>

Also the non-analytical characterization is broken, as well as versions past 1.2.15 for sky130 sigh

lethalbit,
@lethalbit@chaos.social avatar

@North it is still fairly new, but I don't really think that excuses it from just being awfully implemented,

and AFAIK there have been a few validated runs of OpenRAM from MPW 1,2,3, although afaik Caravel has been broken as well for a while so shrug who knows if they work as expected.

lethalbit,
@lethalbit@chaos.social avatar

@North Yeah I get you, i'm actually actively working on integrating OpenLANE flows directly into Torii, which is my Amaranth-HDL fork, to hopefully make things easier for that kinda thing.

And as for the harness, I'm pretty sure it's sorted mostly science MPW4, but I could just be entirely wrong about the Caravel bits, that's a @matthewvenn question I think

Picking out Mezzanine connectors is hard, especially when you need to think about BOM cost so you can't just use the really really nice samtec one because it costs like 4-6 times what other connectors cost, >.<

I really want to use the samtec LSHM, but 11USD /per connector/ is uh, a bit much, >.<

lethalbit,
@lethalbit@chaos.social avatar

you can't look at this connector and /not/ want to use it >.>
