hello everyone.I am trying to create DDR3-IP core. I want to connect two DDR3-SDRAM SODIMMs(64bits) in parallel. each SODIMM has two chip selects pins. so the case needs four chip selects. I try to do so in QuartusPrime 15.1. but I only can select two chip selects.( see attached file ) I think old version of QuartusII could set bigger number, because in that time I set the number directory. how can I set lager number? or can't I do that?

hello sstrellthank you. I am using CycloneV (5CGXFC9...) if I need to create two separate instances, which means that data bus can not be shared right? I don't have enough pins for the second IP.

I'm pretty sure that if you use the hard IP (not the soft controller) in Cyclone V, you can use ping pong phy. Try adding the ip and check the parameter editor for the option.
