Hello. I'm new to FPGAs/CPLDs, and am doing a project with the MAX V 5M160ZE64A5N CPLD and am getting timing failures with a 100MHz clock.

The 100MHz clock is clocking I/O and generating time delays in the logic circuit. I have used the Timing Analyzer and SDC file to constrain the clock, as well as the I/O, however I am getting errors ...
