General Description:
Does ringing (overshoot and undershoot) compromise the reliability of an FPGA device?


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.
