Fairness constraints are crucial in formal hardware verification, ensuring realistic system behaviors by requiring certain actions to occur infinitely often in infinite executions. They eliminate unreasonable counterexamples and help verify properties under practical assumptions about system behavior.
There are three main types of fairness: weak, strong, and unconditional. Each type plays a specific role in modeling different aspects of hardware systems, from arbitration protocols to resource allocation. Understanding these constraints is key to effective formal verification of complex hardware designs.
