TPS48111Q1EVM: About Q1/Q2 EVM SOA cal result

Part Number: TPS48111Q1EVM


Tool/software:

Hi team,

Could you please help clarify why the calculation tool fails the SOA when using the EVM's MOSFET specifications?
If your calculation results can pass, please send me your results.

My design is below

Vin=40~50V Io=50A Cload=330uF

MOSFET= SM1A14NHLD*2 (Back to Back) *4 The number is the same as EVM.

Another question is what sequence of INP and INP_G? 

No MCU to control, and need a delay between  INP and INP_G? thanks
