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? Error (14566): Could not place 2 periphery component(s) due to conflicts with existing constraints (2 pin(s)) Error (175020): Illegal constraint of pin to the region (89, 69) to (89, 80): no valid locations in region Info (14596): Information about the failing component: Info (175028): The pin name: WE // Write enable Info (14597): No legal location could be found for this component out of 1 considered location(s).
