I didn't know there was a Wikipedia infobox for autistic special interests.

me, having 5 mins ago publicly said im taking it easy for the next two days: feeling guilty about not working hard enough

lofty,

@eniko see, I read this, and my immediate reaction is "you're gonna have to spend the money you get from kitsune tails on therapy to recover from developing kitsune tails".

I've been having a lot of fun playing Rabbit and Steel.

Too bad I suck at it though.

lofty,

@ChiralTheAlien it's a diet bullet hell, but my reflexes are getting a bit better now that I'm learning the patterns.

Back on my bullshit in a limited capacity, doing some therapeutic stupid stuff. Today: which of the 7400 series chips are still being made at a vaguely reasonable price? Because I have Plans, and they involve quite a bit more than just logic gates and flip-flops.

lofty,

@danderson @petrillic if only someone wrote a Yosys script to convert logic to those weird chips.

lofty,

@danderson That's the skeleton of it; I was very new to Yosys when writing it, and I think I'd do things very differently these days.

GENLIB is so much easier to use than Liberty

Maybe if I have a moment I can write an example GENLIB file for this.

Seems like my goal at work is to add a bunch of metrics to nextpnr.

So, is there any information people would like to have available?

lofty,

@azonenberg

It's on the list, and it shouldn't be too hard to add. (Currently it has a heat map of routing by wire type)

where's a set theoretician when you need them.

lofty,

@ChiralTheAlien oh, you have no idea.

lofty,

@ChiralTheAlien I should add this as an endorsement :p

I am doing my best to be too professional to vaguepost, but I really, really want to.

at some point I'm sure I will accept that other people perceive the things I do as witchcraft just as much as I perceive the things others do as witchcraft.

I'm an abandonware radicalist; not only should abandoned software have its source released, abandoned hardware should be opened up to development to stop it being ewaste.

YosysHQ has two new employees, and I'm pretty sure I won't live up to whatever preconceptions they have of me.

Two weeks of this server being up, and the only real issue I've had is that I've had to set up a watchdog for when what I think is the NIC chokes.

Could be worse, I think.

yeah, jeez, music doesn't pay well.

aesthetically speaking, what is your favorite wavelength of electromagnetic radiation? — 370nm +/- 20nm; I like the night club fluorescence you get. runner-up might be the ghostly blue of cherenkov radiation. https://retrospring.net/@Ravenslofty/a/112084121309811037

Hello! I have managed to pry myself from sleep with great difficulty. It's Monday, it's hot, and it's sweaty. I'm going to need all the coffee today....

lofty,

@ChiralTheAlien well, my fedi server hasn't crashed today, so that's a good start to the day.

my favourite part of risc-v is how it confidently asserts there are only five instruction formats, and then you read the encodings and you have:

  • register fields being used as shift offsets
  • fence splitting an immediate into three different fields
  • fused multiply-adds to annoy anybody who assumed RV only needed two register file read ports
  • funct7 using the same bit to mean different things
  • the Zb instruction lovingly stomping on funct7 for opcode space
  • did I mention that RV is already running out of encoding space because of RVC?
