Altera forum is dead as ever on this issue.. I have a DDR3 controller,
but in order to test it i have to get the Quartus to interface to my
DDR3 stick. As in connect the physical pins to my project. This it does
not do for some reason I cant really put my finger on. But I get "those"
warnings. Could this be due to termination IE can be ignored or?

with existing constraints (2 pin(s))
