Hello everyone. I've been messing around with Digilent BASYS2 board. I want to develop my own breakout board soon using the Xilinx Spartan 3E-100 Chip. I understand that the chip needs to be powered at 3.3V, 2.5V, 1.8 and 1.2V, but I want to know other things to consider for FPGA board design? For example, how is the JTAG connected?
