Synchronous Circuit
A digital circuit where all state changes are coordinated by a common clock signal.
Detailed Explanation
Synchronous design uses a global clock to sample inputs and update outputs simultaneously across all flip-flops. This simplifies timing analysis—designers only need to ensure combinational delays meet setup and hold requirements.
Synchronous methodology dominates digital design due to its predictability and tool support. Even "asynchronous" systems typically use locally synchronous domains with careful clock domain crossing.
