Hi Gokul,
you are right and they mention that Optisystem is not forward compatible, This may be Optiwaves Business policy, I don’t see any other season for this. I have worked in many simulation platform but this one is the first to face this problem. In most of the software they add new features in newer versions and those are not available for older version users, This may be something acceptable for the licensed users but the way Optiwave is doing is really not acceptable. I asked if there is some way to convert those file made in Optisystem 14 to support in Optisystem 13. Still There is no answer.
So dear Gokul it would be better to design the all the same file again in optisystem 13. it would be waste of time for waiting help in this issue.
Regards,
Dhiman
