SystemC is a C++ library for modeling concurrent systems, and the reference implementation of IEEE 1666-2011. It provides a notion of timing as well as an event-driven simulations environment. Due to its concurrent and sequential nature, SystemC allows the description and integration of complex hardware and software components. To some extent, SystemC can be seen as a Hardware Description Language. However, unlike VHDL or Verilog, SystemC provides sophisticated mechanisms that offer high abstraction levels on components interfaces. This, in turn, facilitates the integration of systems using different abstraction levels.
