#Breaking-Taps #video about how he got silicon #electronics fabricated (through #WaferSpace #MPW, not a multi-project chip). He settled on a MOV machine (transport-triggered architecture) called BTTAP, designed it in the Spade #HDL, synthesized it with Yosys and ABC, and simulated it for SKY130. Includes animations of some analog simulations. He tested his RTL (?) in cocotb instead of Verilator and viewed his waveforms with Surfer instead of gtkwave. Then he used LibreLane, which wafer.space provides as a #Nix Flake, to get from a netlist to GDSII. Finally wafer.space got it fabbed through GlobalFoundries’ GF180 process, which I didn’t know had an open-source PDK, in only 3-4 months. Wafer.space got some of the chips packaged as COB with transparent epoxy. He got about 1000 chips. From looking at MPW pricing in the past, I’d estimated that this cost him about US$2500, but I think it was actually US$5000. wafer.space GF180MCU run 3 is in December, early-bird price for a quarter-size chip (1.94 × 2.53 mm) of only US$2000.

on 02015-08-26#Nix has .debs, RPMs, source packages, etc. Includes .debs for Wheezy. The .debs are kind of cruddy: they don’t create the /nix directory or an init.d script to start the nix-daemon, and the package description is “Package created with checkinstall 1.6.2”. It looks like they include a bunch of systemd bullshit, even though Wheezy doesn’t use systemd. Also, it doesn’t create the ‘nixbld’ group. This .deb distribution is useless.
