Just announced at DAC in San Francisco the Open SystemC Initiative (OSCI) has announced the completion of the TLM-2.0 Reference Manual for public release. The manual is a formal description of the TLM-2.0 APIs and semantics, and is the result of intensive work by the TLM WG over the past year. It clarifies the original specification, incorporates minor changes for consistency and completeness, and is accompanied by an update of the TLM library: release 2.0.1. 

Doulos has been engaged in developing SystemC-based methods and training programs since 2000 and is an active contributor to the work of OSCI. You can read a complete technical explanation of what's new in TLM-2.0.1 here.
