C2000WARE-DIGITALPOWER-SDK: Compesator Designer bode plot varies from actual data in sfra.csv file

Hello TI,

I have extracted the open loop response by running sfra. I have the attached data for your reference. When I load in compensator the bode plot is totally off. When I plot manually then the data points are matching the plot.

Why compensator designer is displaying zig zag data when the actual data is kind of smooth curve.

Here is the data : SFRAData21_January_2026_12_57_50.csv .
library version C2000Ware_DigitalPower_SDK_5_06_00_00

With regards
