Arty MPW Tester
The Arty MPW Tester is a simple expansion board compatible with Digilent Arty A7 development kit. This board connects IO signals from the Xilinx Artix FPGA located on the Arty board to an open hardware Caravel breakout board. The Caravel breakout board allows testing ASIC designs prepared for Multi Project Wafer (MPW) shuttles and fabricated with the SkyWater Process Design Kit (PDKs).
