You have just 10 days left to get your #ASIC design submitted to our TTSKY25b shuttle!
There are still 70 early bird dev kits left, which mean you can do a full custom tapeout for just €185!

It's a CPU module for a possible RISC-V hackable computer.

This idea for a RISC-V machine similar to RC2014 seemed like a good one so I've been thinking about it for the last few days.
I've put together a rough plan for how it might be done - I'm interested in what people think!

Grarkle. My laptop spontaneously powered off while playing Train Sim World earlier (Train Sim World 6 seems surprisingly good, think they've fixed some of the bugs since I last tried it).
Since then, no boot. Windows repair didn't work. Have had to kick off a reset.
