# ghdl-yosys-blink

Blink an LED on an FPGA using ghdl, yosys and nextpnr - a completely

Open Source VHDL synthesis flow.

## Supported Hardware

Right now only Lattice ECP5 boards are supported, but you should be able

to use anything that yosys and nextpnr supports. I've personally tested

the Lattice ECP5-EVN board and the OrangeCrab.

## Prerequisites

You can install the latest versions of GHDL, ghdlsynth-beta, yosys, prjtrellis

and nextpnr if you want, but thanks to the GHDL Docker project we have Docker

images for everything!

It also works fine with podman if you prefer that to Docker.

## Building

```

make

make prog

```
