MCF5372, observed distorted output using the model MCF5372LCVM240.ibs

[sms2]

Hello Everyone,

Request to understand , the reason about the high overshoot/Undershoot, Ripple,Non monotonicity for the Address/Data ,SDRAM,CPU_CLK signal using the model "MCF5372LCVM240.ibs".

pad_rfc_33_01,20pF Drive Strength is the IO used.

FYI,  have replaced the controller and observed  the signal using different controller, the result looks acceptable.

Kindly help me to understand about the model.

Hi,

Unfortunately, I do not see your mentioned overshoot/undershoot situation with attached IBIS file.
