Generic Architecture Example

This contains a simple, artificial, example of the nextpnr generic API.

• simple.py procedurally generates a simple FPGA architecture with IO at the edges, logic slices in all other tiles, and interconnect only between adjacent tiles

• simple_timing.py annotates cells with timing data (this is a separate script that must be run after packing)

• report.py stores design information after place-and-route to blinky.txt in place of real bitstream generation

• Run simple.sh to build an example design on the FPGA above
