Which consequence results from timing variation in clocked synchronous digital processing?

💡 Explanation

Timing variation, also called clock skew, may cause metastability when a signal arrives close to the clock edge; state transitions become undefined because the flip-flops resolve to incorrect values, therefore the system enters an undefined state rather than a predicted state under synchronicity.
