Open Core Protocol International Partnership Releases OCP SystemC Channel Version 2.1.2

PORTLAND, ORE — April 11, 2006 — Open Core Protocol International Partnership (OCP-IP) today announced the availability of the SystemC Transaction Level Monitor (TLM) Channel version 2.1.2. The new features in version 2.1.2 improve model interoperability, resulting in better productivity in system level modeling.

Version 2.1.2 incorporates several enhancements and now includes a TL3 channel based on the OSCI TLM version 1.0. The new TL3 provides the ability to model communication more abstract than bus interface transactions; for example, it now supports message-passing communication. In addition, this new feature represents unification of OCP and OSCI TLM work. Version 2.1.2 also has a new common access interface for the connection of transaction monitors, assertion checkers, etc to the OCP channel at TL1, TL2 and TL3 abstraction levels. This feature ensures convenient EDA tool support for the OCP channels. Tools can now be connected to the channel in a modular fashion without requiring knowledge of internal channel operation.

This version additionally includes a new set of fully configurable abstraction layer adapters for TL0 toTL1 and TL1 toTL2. The adapters are no longer just examples, but support full OCP interface right out of the box. This version is fully compliant with SystemC 2.1v1.

Work on the compliance models was completed by the OCP-IP System Level Design Working Group including representatives from: CoWare, Nokia, Sonics, TI and GreenSoCs.

“Our System Level Design Working Group is comprised of experts from leading companies engaged in Transaction Level Modeling,” said Ian Mackintosh president OCP-IP. “We have shipped tens of thousands of copies of our TLM work over the years and are particularly proud of the quality and ongoing evolution of the modeling standard pioneered.”
