Now Available: Encounter RTL Compiler 10.1

Comments(2)Filed under: Logic Design. Power Shut-Off, Synthesis, multi-vt, turnaround time, RTL Compiler 10.1The latest major release of Encounter® RTL Compiler is available for download (look for "RC101").  Some of the highlights include:

Quality of Silicon improvements.  A lot of work continues to go into improving results, especially physical results. We have seen some early-adopter partners gain some significant area, timing, and power savings (these tend to be design-dependent and constraint-dependent, of course).

Multi-vt algorithm improvements. We have done a lot of work in the multi-vt engine to deliver the best balance of all your design goals. With 10.1.100, the low-effort multi-vt setting will now focus on minimizing leakage power with no area penalty. Medium and high efforts will still prioritize leakage optimization over area, and these effort levels have seen reductions in leakage power versus previous releases. And the default multi-vt effort setting is now medium-effort.

Runtime improvements for large designs. This continues to be a focus area for the team, as the size of designs being synthesized is growing. RC comfortably turns around 1M instances (that's 3-4M gates) overnight, and we are looking to speed things up even more for 1M+ instance designs.

Floorplan tweaking. When you identify an issue in RC-Physical that is floorplan-related, wouldn't it be nice to be able to try tweaking something in the floorplan yourself to see if it helps? This should help speed up resolution of these types of issues, since you don't have to bother the physical design team and wait for them to get a chance to make the change.

Rapid re-synthesis. This is a new capability in RC-GXL that speeds up turnaround time when trying different things on the same design. So after you synthesize a design and want to change a constraint, or attribute, or RTL; as long as the change is fairly localized, the turnaround time will be much shorter than a full re-synthesis.

Superthreading no longer requires GXL. Again on the faster turnaround theme, we want everybody running RC as fast as possible! So superthreading no longer requires an RC-GXL key to enable it.

DFT.  We have done a lot of work over the past 18 months to make test logic insertion work seamlessly within synthesis. Now that we feel it is well-integrated, we are starting to build out the feature set some more. This release features improved power estimation of test logic with the "report_test_power" command. It also adds the ability to insert asymmetric compression logic to reduce pin count in compression mode. And finally you can insert MBIST that can be accessed directly without having to go through the TAP.

Those are the major items -- there are a lot of smaller improvements as well. And we have more planned for the second half of the year, so stay tuned. We will be doing update training throughout the second half of the year, so please contact your local Cadence synthesis expert for details or input/feedback on new releases.
