About SystemC

The Language for System-Level Modeling, Design and Verification

Ratified as IEEE Std. 1666™-2005, SystemC™ is a language built in standard C++ by extending the language with the use of class libraries. SystemC addresses the need for a system design and verification language that spans hardware and software. The language is particularly suited to model system's partitioning, to evaluate and verify the assignment of blocks to either hardware or software implementations, and to architect and measure the interactions between and among functional blocks. Leading companies in the intellectual property (IP), electronic design automation (EDA), semiconductor, electronic systems, and embedded software industries currently use SystemC for architectural exploration, to deliver high-performance hardware blocks at various levels of abstraction and to develop virtual platforms for hardware/software co-design.

Why SystemC?

An SoC is literally a system on a chip, consisting of both silicon and embedded software. Its design involves complex algorithm and architecture development and analysis similar to that performed in system design – a trade-off process that determines critical metrics, such as SOC performance, functionality, and power consumption.

Consequently, design tools must deliver orders-of-magnitude improvement in productivity at both architectural and implementation (RT and physical) levels. Moreover, tools must support a methodology that enables the early development of embedded application and system software, long before the availability of the RTL design or silicon prototype. Failure to achieve the requisite improvements in design productivity would result in missed market windows, and exploding design costs.

SystemC is a single, unified design and verification language that expresses architectural and other system-level attributes in the form of open-source C++ classes. It enables design and verification at the system level, independent of any detailed hardware and software implementation, as well as enabling co-verification with RTL design. This higher level of abstraction enables considerably faster, more productive architectural trade-off analysis, design, and redesign than is possible at the more detailed RT level. Furthermore, verification of system architecture and other system-level attributes is orders of magnitude faster than that at the pin-accurate, timing-accurate RT level.

The SystemC community consists of a large and growing number of system design companies, semiconductor companies, intellectual property providers, and EDA tool vendors who have joined together to support and promote the standard.
