Automatic verification of pipelined microprocessor control [chapter]

Jerry R. Burch, David L. Dill
1994 Lecture Notes in Computer Science  
We describe a technique for verifying the control logic of pipelined microprocessors. It handles more complicated designs, and requires less human intervention, than existing methods.  ...  Empirical results include the verification of a pipelined implementation of a subset of the DLX architecture.  ...  As a result, one verification run can check the control logic of pipelines with any combination of values for these parameters.  ...
