Define static hazards and dynamic hazards; provide an example of each.

Define static hazards and dynamic hazards; provide an example of each.

• A. Static hazard: a function that should remain at 0 momentarily drops to 1 due to delays; Dynamic hazard: multiple changes cause unintended transitions.
• B. Static hazard: a function that should remain at 1 momentarily drops to 0 due to delays; Dynamic hazard: multiple changes cause unintended transitions during a single input event; mitigated by adding redundant terms or synchronizing paths.
• C. Static hazard: glitch due to clock skew; Dynamic hazard: glitch due to supply noise.
• D. Static hazard: occurs only in asynchronous circuits; Dynamic hazard: occurs only in synchronous circuits.

Answer: (B)
