PSPICE-FOR-TI: Pspice model of TPS43060 not switching

Part Number: PSPICE-FOR-TI
Other Parts Discussed in Thread: TPS43060


I am trying to simulate the TPS43060 in Pspice. But, the PGOOD of the TPS43060 does not go high. From the datasheet, I do not see a reason why this would be so. Vin = 20V, Vout required = 40V, Can someone let me know what I am missing?

I am attaching the schematic of the Pspice design and the corresponding graphs. I have used the TINA reference design for the TPS43060 which works fine and attached those graphs for reference as well.
