WebThe purpose of I/O timing constraints is to ensure a reliable interface with the outer world: They guarantee that each signal from the outer world arrives reliably to the relevant flip-flop on the FPGA. Likewise, they also make certain that each signal from the FPGA to the outer world arrives reliably to the flip-flop on the external component.
