Power IR/EM vs Voltus-Fi

There are two flows for IR/EM analysis for analog/mixed-signal designs - Voltus-Fi L and Voltus-Fi-XL. Voltus-Fi-L works on Quantus (QRC) generated extracted views, while Voltus-Fi-XL works on a transistor-level DSPF.

Where did you see the reference to 'Power IR/EM' as a tool?

Can you also tell me the IC version you are using? Going back to some older IC releases, you will find 'Power IR/EM' as an available option in Layout Editor. This was to allow launching VPS-L. VPS-L has now been replaced by Voltus-Fi-L: they both work with extracted views, but the GUI interface for Voltus-Fi-L is better and is same is Voltus-Fi-XL. In the latest IC617 versions, you will see VPS-L, Voltus-Fi-L and Voltus-Fi-XL, so it is more obivous what you are running. If you are new to these flows, I'd recommend using Voltus-Fi-L or XL.

Thank you Saloni.

I'm new in this flows and only study them. I'm using IC617.
I read the documentation and see two manuals.
1) "Voltus-Fi Custom Power Integrity Solution User Guide"
2) "Power IR/EM User Guide"
And I understand that these are similar but different products.
I would like to understand why two products?
What is their difference, dignity, flaws?

Hi Andrey,

Voltus-Fi is our new EM/IR solution, while Power IR/EM (or VPS-L) is older. With new products, we put in new functionalities and features, so if you are starting now, please use Voltus-Fi. The old product is still supported for some legacy users who are in the process of migrating over to Voltus-Fi. There are Rapid Adoption Kits available on Voltus-Fi which you can explore:

Ok, thanks for the answer, Saloni.
