Glitch is kind of short duration pulse, mostly because of cross talk from a neighbour clocking or switching circuits or sudden turn on/off in the circuit of interest. But it could dangerous or not it depends on your circuit requirements. Therefore, elimination of glitches in digital systems implemented on hardware platforms, such as Field Programmable Gate Arrays (FPGAs), is imperative for low power and secure designs. However, a targeted application of glitch elimination techniques requires precise detection of possible glitches. While post place-and route simulation allows the user to detect and display glitches, it cannot ... How can we prevent race condition: Normally, in digital designs, as long as setup and hold checks are met for each flip-flop, we do not need to worry about the race conditions in the design under consideration.But, there are some conditions like the output of the above AND gate might be used as a clock for some flop. In that case, we need to consider the race condition.
