Synthesizing TLM Models

Architectural exploration and design implementation all too often are two separate tasks implemented by two completely separate groups. Once a high-level TLM model has been tested and approved, it goes on the shelf while a designer starts from scratch to generate a synthesizable design.

While this may sound simply wasteful, things aren’t so simple. TLM models are abstract, using busses and transactions. An RTL design has to specific signals at the individual level – the TLM model doesn’t have that, so the TLM model tends not to be particularly useful as a starting see for implementation.

Calypto is trying to address that, as they described in a discussion at DVcon. They’re making available a set of interfaces that can be used at multiple levels of abstraction – and, specifically, which can be used to go from architecture to synthesis. They’re starting with AXI, but plan others.

The tie-in with Mentor here is obvious. First off, you may remember that they bought Mentor’s Catapult C. So they have a stake in the high-level synthesis game now. Second, Mentor has a technology that they call Multi-View that allows a single model to be used and viewed with different levels of abstraction for different purposes.

These technologies converge in this IP announcement. You can find more in their release

As we seek to go faster and faster in our systems, heat grows as does the noise from the cooling fans. It is because of this heat and noise, many companies are investigating or switching to submersible cooling (liquid immersion cooling) options. Over the last few years, subme...
