The Use of SystemC for Design Verification and Integration Test of IP-Cores

The current trend of systems on silicon is leading to System-on-Chips with embedded software and hardware components. Design simplification is becoming necessary to respect the target time-to-market of SoCs, and this goal can be obtained by using predesigned IP-cores. However, their correct integration in a design implies more complex verification problems. The SystemC language allows one to create and integrate accurate models of software algorithms, hardware architectures and interfaces for SoCs. In this paper, characteristics of the language are exploited to define a design verification framework for integration-test of IP-cores. Intellectual property of cores is guaranteed by adopting-a client/server simulation architecture and by allowing functional test generation on faulty IP-core models without disclosing their internal structure. Moreover, the methodology can be applied to mixed descriptions based on VHDL and SystemC, since an abstraction layer has been defined allowing clients and/or servers to be indifferently described in VHDL or SystemC.
