Can any1 please elaborate on what are combinational loops. What are their effects and how do we break them....This topic is posted previously but doesnot have any replies...
Combinational loop, simply put, is combination logic with feedback. Once combination logic has feedback, it is usually no longer combination logic, but sequential logic.
Combinational loop causes major issue with STA. STA tool will simply break it and issue a warning. It may also cause dsign to have race conditions and unpredictable behaviors.
