Sequential Logic
Sequential logic depends on present inputs and stored state. Flip-flops, counters and registers are common examples and form the basis of synchronous digital systems.
CORE IDEA
State is stored
ENGINEERING VIEW
Clock edges commonly control state changes
WHAT TO CHECK
Counters and registers are sequential structures
REMEMBER
Timing and setup/hold behavior matter
Engineer’s checklist
- State is stored
- Clock edges commonly control state changes
- Counters and registers are sequential structures
- Timing and setup/hold behavior matter
KEY TAKEAWAY
Digital behavior is physical behavior. When firmware and expectations disagree, measure the signal instead of guessing.
