On Power Awareness in RTL design analysis: Update to a Brian Bailey-designated Top Ten Atrenta article

Wednesday, October 10th, 2012


Narayana Koduri’s article on Power Awareness in RTL Design Analysis was the second of two Atrenta articles that EE Times editor Brian Bailey named as the ten most-read contributed articles published in EDA Designline.    Along with number one article Understanding Clock Domain Issues  by Saurabh Verma and Ashima Dabare, Atrenta appears to be the only company with two articles in this top ten list.

So even though his article appeared in July 2012, we asked Narayana to give us an update on what he sees as the power awareness challenges.  Here’s what he had to say.

Ed:  Narayana,   your article sure addressed a hot topic in SoC design. And judging by the readers you got, the design community liked what you had to say.  What can you add to your July 2012 article?

Narayana:  Thanks Ed.   From what I can see, due to aggressive low power requirements, power domains are being implemented in a growing number of SoC designs to reduce both leakage and dynamic power.

Ed:  How so?

Narayana:  UPF or CPF can be used to define the power intent to capture information such as power domains, level shifter requirements, isolation cells, retention cells, power switch cells, etc. These specifications will help implementation tools and verification tools to deal with the power intent properly.

Ed:  So how best to deal with power intent?

Narayana:   RTL tools that verify aspects of the SoC such as clock domain crossings, testability, timing and routing congestion need to be aware of the power intent. If not, the verification is not complete and this may lead to design failures or a costly re-spin of the design. This need for power-aware verification is driving new requirements in the EDA tool flow.

Predictions 2012 – Standards and Social Media

Thursday, January 12th, 2012

This year, we’ll see an old standards battle get resolved. Now that all the players are participating in the IEEE Standard 1801 project (IEEE Standard for Design and Verification of Low Power Integrated Circuits), we can finally put the UPF-CPF debate to rest. Let’s hope that peace will reign and the temptation to fight one more time about a single low power standard will be overcome.

Social media will become less of a curiosity or a perceived waste of time for engineers. We’ll see more EDA customers helping answer each other’s questions and sharing more information (nothing proprietary, of course). LinkedIn discussions will have more depth, not simply people posting “read my blog”.

Facebook will remain more of a social vehicle, and for many engineers of our generation, a misunderstood channel. YouTube videos that provide good content – “how-to” and learning opportunities – will become popular. Twitter will remain a mystery for most, while a minority will find it of much value (include me in the minority). Marketers who spam social media channels with marketing-speak will be shunned. And, we’ll have some great guests on Conversation Central radio.
