A simple example design, based on the Digilent BASYS3 board
===========================================================

This example uses Yosys for synthesis and Xilinx Vivado
for place&route and bit-stream creation.

Running Yosys:
  yosys run_yosys.ys

Running Vivado:
  vivado -nolog -nojournal -mode batch -source run_vivado.tcl

Programming board:
  vivado -nolog -nojournal -mode batch -source run_prog.tcl

All of the above:
  bash run.sh
