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

Do you ever use the same constraint templates in multiple projects? Now, with PADS Professional VX.2.5, you can easily import and export constraints from one project to the next. Constraint templates enable application of complex rules to multiple nets. They help ensure a smo...

In the video above, it might not appear that much is taking place, but just like with transformers there is “more than meets the eye.” Alright, that was corny, and I am mildly ashamed, but Nanosecond Event Detection for shock and vibration is nothing to be ashamed...

Let'€™s face it: We'€™re addicted to SRAM. It'€™s big, it'€™s power-hungry, but it'€™s fast. And no matter how much we complain about it, we still use it. Because we don'€™t have anything better in the mainstream yet. We'€™ve looked at attempts to improve conven...
