packing for hollidays, a couple of FPGAs just in case. what fmax can #femtorv-tordboyau reach on the #ULX3S, on the OrangeCrab and on the IceBreaker ? We shall see !

que también corre Linux 😃

So let's pack our luggage for our journey. You will need hardware and software. My favourite FPGA boards are:
- IceStick ($35), minimalistic, just enougth to start
- IceBreaker ($60), more comfortable
- #ULX3S ($100), fantastic ! large FPGA, SDCard, HDMI, SDRAM

One of the great things about a FPGA: Every pin has HW PWM capability (if you write the HW that is)... especially those pesky eye searingly bright debug LEDs
#fpga #ulx3s

#riscv is pretty neat. I spent some time creating a basic RISC-V core in verilog and the process is really interesting. The image on the left shows my CPU core executing a program which computes fibonacci numbers in simulation. The other image shows the same core executing the same program on my #ulx3s #fpga. Testing in simulation first proved to be invaluable for discovering bugs early.

ULX3S crowd funding campaign is live!

ULX3S is powerful open hardware FPGA dev board based on Lattice ECP5 with a bunch of cool stuff on the board and it is supported by the open source toolchain: https://www.crowdsupply.com/radiona/ulx3s
