Cyclone V DDR3 termination resistor

Hello, I am currently working on the design of a Cyclone V SE board with 2 DDR3 memory chips. I am wondering if it is necessary to have the termination resistors for the adress / command sign...

Hi,

Thanks, i know this document and at page 1-50, it is written that we have to place termination in the case of DDR3 components in a fly by topology which is not supported by the Cyclone V.

But i don't see the case of the T-Topology.
