Abstract

Huge new design challenges for system-on-chip (SoC) are the result of decreasing time-to-market coupled with rapidly increasing gate counts and embedded software representing 50-90 percent of the functionality. The exchange of system-level intellectual property (IP) models for creating executable specifications has become a key strategic element for efficient system-to-silicon design flows. Because C and C++ are the dominant languages used by chip architects, systems engineers and software engineers today, we believe that a C-based approach to hardware modeling is necessary. This will enable co-design, providing a more natural solution to partitioning functionality between hardware and software. In this paper we present the design of SystemC, a C++ class library that provides the necessary features for modeling design hierarchy, concurrency, and reactivity in hardware. We will also describe experiences of using SystemC 1) for the co-verification of 8051 processor with a bus-functional model and 2) for the modeling and simulation of an MPEG-2 video decoder.
