Formal verification using parametric representations of Boolean constraints

We describe the use of parametric representations of Boolean predicates to encode data-space constraints and significantly extend the capacity of formal verification. The constraints are used to decompose verifications by sets of case splits and to restrict verifications by validity conditions. Our technique is applicable to any symbolic simulator. We illustrate our technique on state-of-the-art Intel(R) designs, without removing latches or modifying the circuits in any way
