Benchmark

non-incremental/QF_LRA/sc/sc-19.induction2.cvc.smt2 

Fully parameterized specification and verification of a synchronizer   
circuit modeling metastability at various levels of refinement.     
A paper describing this specification, to be published in Designing     
Correct Circuits (DCC), 2006, is available from the authors.
