Abstract
To perform functional verification of a digital design that includes one or more datapaths, a formal verification system includes a datapath abstraction tool. The datapath abstraction tool detects a datapath in a circuit design and performs an appropriate abstraction of the datapath. The tool may also deduce datapath elements from identified ones as well as link the abstractions of particular datapath elements. The abstraction tool then passes the circuit design with the abstraction to the verification software to simplifying the formal verification process.
