UCC23513: [PSpice model] Questions about simulation results

Hi Team:

I am using UCC23513 for simulation purpose to check the propagation delay, because the  IF is hard to catch, so I decide to use PSpice to double check the delay.

Here is the simulation SCH.

Result:

1.the propagation  delay is about 592ns, which it is far away from the 105-ns (maximum) value ,can you help to check what `s the problem?

 tks again,
