I recently created a System Verilog code to measure latency between two incoming pulses. I tested it with buttons on the board first and it worked. Now that I'm using the PMOD ports, however, it just keeps on reading that the pulses are always high, though nothing is connected to them. The only thing that I've changed is the XDC file. Why can't I use the PMOD Ports?
Using a multi-meter, I have found that the two ports I use are around 30-50 mV each. When I changed the ports on the xdc file to use JB and JC PMOD, the ports that I connect to still read 30-50 mV. No other ports read this voltage.
