It seems that Mentor Graphics have lost the last change to get back in Signal Integrity and Power Integrity for ever while Ansys, Cadene, Keysight are renewing thier stuff. I don't know what exactly Mentor team think about Hyperlynx. However, I think following items Mentor Graphics may take
1) Mergere Hypelrynx and Hyperlynx DRC A new GUI and API framework is a must.
2) Add Flo.pcb into Hyperlynx. Ansys Siwave now have icepack solver in Siwave.
3) refine Nimbic(accuracyand speed) technologies and the interface for ECAD data
4) Accqures Simbeor to provide a fast GHZ channel synthesis solution.
5) refine integration between XpeditonPCB and Hyperlynx .
