 Before we run our program, we must first map the signals to pins using the Nexys4_Master.xdc file we imported. To do this, we will open Nexys4_Master.xdc. Inside this file, we will see how Vivado maps signals to pins. Each line should be commented out at this point (with #), so it should look something like this. Before we run our program, we must first map the signals to pins using the Nexys4_Master.xdc file we imported.
