Accellera Systems Initiative has released version 2.3.0 of its SystemC open source proof-of-concept library, now available at no charge. Compatible with the newly revised IEEE 1666 "Standard SystemC Language Reference Manual," announced by the IEEE Standards Association in November 2011, version 2.3.0 provides a number of important new features, including support for transaction-level modeling (TLM).

New extensive process control features enable modeling of concepts such as power domains and abstract schedulers. A new first-class events list and a new container for SystemC objects simplify the description of generic and scalable models. In addition, an improved simulation API and a new thread safety mechanism will allow much better interaction with external tools and support for multi-threading.

Documentation has been reorganized for clarity, and there is a new document highlighting the features added for compatibility with the latest version of the SystemC standard. The library, installation notes and readme files have been updated to support installation on the latest operating systems and compilers. To ensure a high quality release, the library has been reviewed and tested by members of the SystemC Language Working Group, and feedback from the recently completed public review has been incorporated in the release.

The standard may be obtained at no charge via the Accellera Systems Initiative-sponsored GET IEEE program by visiting http://www.accellera.org/downloads/ieee/. The newly released version 2.3.0 of the open source proof-of-concept library (and the corresponding regression suite) may be downloaded by visiting http://www.accellera.org/downloads/standards.
