TPS56121: TPS56121 Pspice model error

Part Number: TPS56121
Other Parts Discussed in Thread: PSPICE-FOR-TI

I am trying to simulate a dcdc TPS56121 buck converter circuit but I met a error on TINA and PSpice-for-TI. The error on TINA is "Undefined subcircuit: DELAY."

The error on PSpice is shown below

tran.out.1:
