[IBIS] How to handle > 50% correlation

Hello,

I created an IBIS model of a GPIO cell and correlated the simulation results between using the IBIS model (HSPICE simulation) with the transistor level (spectre simulation).

I used two methods in obtaining the IV and VT curves.

However, the correlation results are 50% off for the risetimes & falltimes for both cases.

Can anyone please advise on what to do in this case?

Thanks & best regards,
Estella
