Mentor's HL synthesis tool now supports TLM

Mentor Graphics Corporation has announced that its Catapult C high-level synthesis tool now supports the synthesis of transaction level models (TLMs).

With the new TLM synthesis flow, abstract TLM models are converted to pin-accurate, protocol-specific, SystemC models, and from there, synthesized to RTL code. Conversely, existing synthesizable descriptions can be converted to TLMs. The flow supports standard off-the-shelf bus interfaces, including the ARM AMBA bus family, as well as custom protocols.

Mentor says this new capability provides an essential link between virtual prototyping and HLS-based hardware implementation. Traditionally, these two activities have been separated by incompatible abstraction requirements: virtual prototyping relying on fast and abstract TLM interfaces, and HLS requiring pin-accurate synthesizable models, adds Mentor.

"Eighty-seven percent of the respondents in a recent survey said it was either mandatory or highly desirable to have high-level synthesis tools integrated with ESL flows," said Simon Bloch, vice president and general manager, Design and Synthesis division at Mentor Graphics. "TLM synthesis leverages Mentor's strong technology 'know how' in both high-level synthesis with Catapult C and virtual prototyping with the Vista platform as a pivotal starting point for new levels of ESL flow integration."
