LM5164: why LM5164 cannot simulate buck inverter in TINA?

Tool/software:

hi team

I use LM5164 to design a inverter, Vin = 45V, Vout=-45V. 

when I use it to convert 90 to 50V, it is ok, but simulation is very slowly. 

but for inverter, it cannot support? why? is there any error in this circuit? but from some article, the circuit is simliar.

please help
