| Before synthesizing your design, you will need to create an .xdc file that contains the pin locations of each port in your design. Most of the pins used in this design are the same as pins used in previous designs (buttons, switches, seven-segment display, etc.). However, you will be using a new FPGA pin to connect to the UART/USB transciever and the debug port. | Before synthesizing your design, you will need to create an .xdc file that contains the pin locations of each port in your design.
