While simulating my T1042 processor's address bus with 10 DDR3L memory chips, i found that the driver's(controller) address signal is having overshoot and undershoot of greater than and equal to 400mV. I am using Vtt termination resistor in my design. However, i cannot use series termination on the driver side since it is only recommended for a point to point system. Please let me know what can i do to reduce the overshoot and undershoot? Thank you!
