Specifying and Property Checking the AMULET1 Address Interface

Designing Correct Circuits - Y. Liu & G. Birtwistle - We describe work completed on the specification and verification of the address interface of AMULET1, an industrial strength asynchronous microprocessor designed, fabricated and tested by Manchester University. - AMULET1 is an asynchronous version of ARM, the best selling RISC chip in the 1980's, and now a leading macro-cell. - The address interface is a substantial floor plan element, shared by several processes,which acts as a filter into memory for pc-values, memory swap, and single and multiple load/store operations. - The specification is at the register transfer level and is sufficiently detailed to detect the known deadlocks in earlier designs and verify that the final version is deadlock free. - The specification work was carried out in Milner's Calculus of Communicating Systems (CCS) and property checked using the ConcurrencyWorkbench (CWB). - The work described is post facto - it was started after the AMULET1 chip had been sent for fabrication. - Our website uses cookies to help improve your experience.
