General Description: Does ringing (overshoot and undershoot) compromise the reliability of an FPGA device?
Solution
For all FPGA families, ringing signals are not a cause for reliability concerns. To cause such a problem, the Absolution Maximum DC conditions need to be violated for a considerable amount of time (seconds).
Keep in mind, however, that ringing can create many functional issues, causing glitches, double- clocking, setup/hold errors, etc.
