Hi all, Now I'm using ALTMEMPHY as physical layer interface between my DDR2Controller to DDR2SDRAM on CycloneIII.But when "resynchronisation_successful" signal of ALTMEMPHY is high,my controlle...

18 years agoHello,
I think resynchronisation_successful is success for one of several steps in recalibration. I apologize, that I didn't care for the individual calibration status signals from Altmemphy, cause HP controller encapsulates them. The important point is to reach the final user_mode_ready state. But if an identical configuration as you are operating in hardware could be verified in simulation, I would assume a hardware issue. Did calibration complete succesfully in your hardware version? If so, the basic memory interface function seems to be operational, but data errors for data different from train pattern could occur anyway. Regards, Frank
