Analysis And Verification Of Arithmetic Circuits Using Computer Algebra Approach, Tiankai Su

Doctoral Dissertations

Despite a considerable progress in verification of random and control logic, advances in formal verification of arithmetic designs have been lagging. This can be attributed mostly to the difficulty of efficient modeling of arithmetic circuits and data paths without resorting to computationally expensive Boolean methods, such as Binary Decision Diagrams (BDDs) and Boolean Satisfiability (SAT) that require ``bit blasting'', i.e., flattening the design to a bit-level netlist. Similarly, approaches that rely on computer algebra and Satisfiability Modulo Theories (SMT) methods are either too abstract to handle the bit-level complexity of arithmetic designs or require solving computationally expensive decision or satisfiability …
