質問 15. Explain the concept of blocking and non-blocking assignments in the context of simulation and synthesis.
Blocking assignments are for simulation and represent immediate actions, while non-blocking assignments are for synthesis and represent sequential hardware behavior.
Example:
Blocking: A = B; // Immediate action Non-blocking: A <= B; // Sequential hardware behavior
