PSPICE for TI/ TPS562202

Other Parts Discussed in Thread: TPS562202

Dear Commnity,

I am trying to simulate the TPS562202 module in  Pspice for TI with parametric analysis for feedback resistor tolerance of 1%.

I am getting below error while simulating. 

Kindly let me know what could be the reason.

----ERROR---
