fpga-stuff

Just a playground for me to figure out FPGAs, Verilog, etc. I found the TinyFPGA BX I had bought a while ago, so I'm using that with one of my Mini-I/O 16 boards (of which I should finish assembling the latest batch and put them back up for sale :-) ), so most of the code targets that board for synthesis with the open-source Yosys/nextpnr/icestorm toolchain. Some (slightly) older projects use Icarus Verilog for simulation, but the tutorial I'm currently following uses Verilator.

Before I found my TinyFPGA BX, I was considering picking up an UPduino. That's why there are some UPduino-related bits in here.

You might find the tinyfpga-template useful for your own projects; it's the icestorm template from the TinyFPGA BX repo, modified to use nextpnr instead of arachne-pnr and with Verilator support added (use make verilate to simulate).
