RedHawk-SC

I’m a fan of getting customer reality checks on advanced design technologies. This is not so much because vendors put the best possible spin on their product capabilities; of course they do (within reason), as does every other company aiming to stay in business. But application by customers on real designs often shows lower performance,… Read More


Big Data Analytics in Early Power Planning

Big Data Analytics in Early Power Planning
by Bernard Murphy on 12-13-2018 at 7:00 am

ANSYS recently hosted a webinar talking about how they used the big-data analytics available in RedHawk-SC to do early power grid planning with static analytics, providing better coverage than would have been possible through pure simulation-based approaches. The paradox here is that late-stage analysis of voltage drops … Read More

There’s a familiar saying that you can’t improve what you can’t measure. Taking that one step further, the more improvement you want, the more accurately you have to measure. This become pretty important when you’re building huge designs in advanced technologies. Margins are a lot tighter all round and use-cases are massively… Read More

On the off-chance you missed my previous pieces on this topic, at these dimensions conventional margin-based analysis becomes unreasonably pessimistic and it is necessary to analyze multiple dimensions together. People who build aircraft engines, turbines and other complex systems have known this for quite a long time. You… Read More


Margin Call

Margin Call
by Bernard Murphy on 06-04-2017 at 7:00 am

A year ago, I wrote about Ansys’ intro of Big Data methods into the world of power integrity analysis. The motivation behind this advance was introduced in another blog, questioning how far margin-based approaches to complex multi-dimensional analyses could go. An accurate analysis of power integrity in a complex chip should… Read More
