Hi, I have a cypress CY7C68001 connected to CE3 and 100MHz SDRAM connected to CE0. SDRAM must run at 100MHz. CY7C68001 needs a data write hold time of 10 ns and a address write hold time of 70ns! On a C6713 I can set WR HOLD to 3. With 100MHz ECLKIN/ECLKOUT I can only get 30ns. Any idea how I can get out of this mess without a HW change?

In C6713' datasheet, maximum overshoot and undershoot on input pins is 4V and -0.7V. In my design with C6713, maximum overshoot and undershoot on input pins is 4.4V and -1V. Violation is 0.4V, is it dangerous for my design? How can I reduce overshoot and undershoot without any change in trace delay? Regards Zahra
