A New Generation of ISCAS Benchmarks from Formal Verification of High-Level Microprocessors

摘要

The paper presents a collection of 20 benchmark suites with a total of 1,132 ISCAS Boolean formulas from formal verification of high-level microprocessors, including pipelined, superscalar, and VLIW models with exceptions, multicycle functional units, branch prediction, instruction queues, and register renaming. These benchmarks can be used in research on testing, logic synthesis and optimization, equivalence verification, Decision Diagrams, and Boolean Satisfiability. The most complex formulas have more than 700,000 logic gates.
