philtor 🇺🇦🌻This week experimented with adding a matmul & sorting accelerators (and opcodes for both) to PicoRV32 using the PCPI interface. Also added support for those ops to the Spike RISCV simulator. Yes, Claude helped a huge amount with these tasks which would've likely taken weeks otherwise. The design simulates (Verilator) & sythesizes (yosys) and I can generate a bitstream for both GateMateA1 and ECP5 (OrangeCrab board)

YRabbitGee!
ADC went through #yosys and #nextpnr!
Does it work on hardware? Absolutely not!🤣

Cayetano SantosFully #freesoftware based support for GateMate FPGAs from Cologne Chip [0] just landed in #guix.
It includes #yosys for synthesis, #openFPGALoader for device flashing and #nextpnr for placement and routing.
guix shell -C -m manifest.scm -- make
The whole toolchain runs in a #sourcehut #ci pipeline.

@guix Other than as package manager on top of #archlinux, I’m using #guix for electronics design, mostly #vhdl and #fpga related stuff.
I run simulations with help of #hdlmake using #ghdl compiler, #osvvm for verification, #cocotb for testbenches, #yosys for synthesis, #nextpnr for placement and routing and #openFPGALoader for flashing. Finally, I use my own Guix channel to package gateware and run #ci tests on #sourcehut Guix image. A demo toy example of this runs here

News about GW5 series - PLL went through #yosys, #nextpnr, and #apicula and started working!🍾
At the moment, there are a huge number of crutches, which I plan to remove in the near future and make the appropriate PR.😉 #fpga#gowin#sipeed
poleguy looking for lost tools@PaulaMaddox Well, I've got the gui tool installed and I see I can start with a demo that echoes data back via the Ft+ V2... that seems like a great start.
Crossing fingers.
I'm not worried about an upload tool much. More about design lock in or other anti-patterns.
I'd love to get experience with #yosys and #nextpnr and maybe this will be my excuse to try.
