Today, Many of PCB designers wish to cover EMI Issues in pcb to avoid costed-respins and decrease time to market, especially for those comsumer portable devices where no metal shielding case exits.
It's not easy to design one-pass PBA .Many designers think PI/SI tools can help them to take this challenge, and think the EMI source be in common-mode noise, so they have put much effort to find what happened in the planes. Sigrity PowerSI and Ansoft SIwave are mostly-used tools. Did they get successful? I think not. The darkness of tools be there(Eric have told us). Does Hyperlynx PI can make this dream come to true by it's easy to use and easy to understand? Let's see how they think about the EMI issue( Of course, I never dream the EMI issues can be covered by simple simulation without chip's CPM models which is not available to system designer,aslo not feasible to measure ).
Here I posted the story to introduce what they think about EMI in PBA:
