Stability analysis for A6985

I'm trying stability analysis phase margin and gain margin for A6985 on the eDesignSuite.

I understand that phase margin and fc are showed in bode plot diagram but gain margin is not displayed.

and I cannot estimate it manually due to vertical axis shows less than -20dB.

Do you have any idea to get a gain margin or to extend vertical axis?

Thank you,

Sekiguchi
