16 years agoI'm not sure I understand your last sentence. You don't need to put any constraints on the clock to the sdram, but you must be sure that all the constraints on the other signals to the memory are defined relative to the pin output that gives the clock to the sdram.
AFAIK you only need to delay the clock to the SDRAM if the Timequest report tells you that the timing requirements aren't met, and you must adjust the delay until they are.
