Xilinx Prototyping Board
Some time ago I wanted to try out programming CPLDs in VHDL. I was entirely new to both of those topics and I didn’t have a real need for a CPLD at the time. So I built myself a nice little prototyping board for the Xilinx XC9500XL complete with some push buttons, LEDs a 7-segment display and a PIC16F688 used mainly as a clock source.
