WEBENCH® Tools/TPS54318: Indutor value is changing

Part Number:TPS54318

Tool/software: WEBENCH® Design Tools

Hi,

I have simulated the TPS54318 part with the following inputs Vin- 4.5V to 5.5V Fsw - 1.125Mhz Output - 2.5V @ 3A 1.

When i simulated with above parameter 2 weeks(13/06/2019) before i was getting following results Inductor - 1.5uH and Vout Overshoot/Undershoot - 100mV. 2.

when i simulated it today(03/07/2019), i am getting different results Inductor - 2.7uH Vout Overshoot/Undershoot - 160mV

Could please tell me the reason? We have finalized the inductor part(1.5uH) and Fsw(1.125Mhz) based on the simulation reports.

hareesh.
