Abstract :
This correspondence presents a method for proof of correctness of register transfer level (RTL) parallel control sequences that describe hardware behavior. An RTL language endowed with parallel constructs is presented and its semantics is defined. The semantics includes temporal behavior. An assertion-based proof method is presented for verification of parallel control sequences described in this language. An example is given and comparisons are drawn between proofs of parallel register transfer level sequences and parallel programs. The temporal semantics associated with the language permits the construction and proof of parallel sequences that are not possible with parallel programs. Accessing shared resources outside critical regions is possible and is illustrated.
