In this report, we present a top-down VHDL modeling technique which consists of two main modeling levels: specification level and functional level. We modeled a RISC Processor (RP) in order to demonstrate the feasibility and effectiveness of this methodology. All models have been simulated on a SPARC 1 workstation using the ZYCAD VHDL simulator, version 1.0a. Experimental results show feasibilty of the modeling strategy and provide performance measures of RP design features.
