Hie Sujesh,

just to addon. Like what Alex mentioned, it's not very common to use 1.2V LVCMOS I/O standard for DDR-related applications, =)

However Quartus does not set restrictions based on the "common applications" of the I/O standards.

Since you are new, i recommend you to checkout the Altera web which has a tonne of documentation on many topics that would be helpful to you.

e.g.:

https://www.altera.com/en_us/pdfs/literature/an/an348.pdf

this should be a good guide for you on DDR-related applications, =)

thanks, have a nice day!
