Hello, I think youre ports name in XDC (constraints) file are not the same in your Block Design. May be try to change input name in your Block Design. See you Justin

Hello, I am using PMOD GPS and exactly 1PPS signal as time reference for 5 FPGAs (XCZU3EG). I am supplying PMOD GPS with 3.3V from one FPGA, and the ground is connected bewteen all the five FPGAs and the PMOD GPS. I want to distribute the 1PPS signal from a GPS PMOD to 5 FPGAs. By measuring with the oscilloscope I see that the PPS signal at the output of the PMOD is at 2.2V (blue curve in the attach image). Why is the PMOD output not 3.3V ? If I put a 3V cell battery, it will improve the output voltage ? Thank you Justin
