Error when simulating ACPL-C797

[Maggie97]

I am trying to simulate this sigma-delta converter(ACPL-C797) in Multisim, but it shows "Transient Time Point Calculation Did Not Coverage". Has anyone also face the same problem? I had attached the file and any help on how to fix this problem will be appreciated. Thanks.

Seems to be a similar behavior.
