FPGA Magic: Drag-and-Drop Updates, Slots, Clock Control & Serial in One Component
This single extra in your BOM will let you shoot bitstreams via a USB drive, get dynamic clocking and a USB serial for your FPGAs, all in a cross platform way.
Riffpga gives you all this, is free and open-source and is designed to be extensible. See how it was made and how you can make the most of it.
