The Gain and Phase Margin Plot does not define default bounds. The Check Gain and Phase Margins block defines default bounds and enables these bounds for assertion. You can view the margins in a table or on a Bode, Nichols, or Nyquist plot. For more information on frequency domain analysis...

(s) + − Figure 1: Solution using Matlab For K = 1, the Bode plot is shown in Figure 2. The plot is obtained using the Matlab command margin. From the graph, the phase margin is 3.8658 ◦ , and the gain margin is 0.56057dB. None of these margins is regarded as acceptable (...

Gain and phase margin can be measured as long as you have a loop analyzer. Please refer to the blog below, https://e2e.ti.com/blogs_/b/powerhouse/archive/2015/05/05/power-tips-how-to-measure-bode-plots-with-dcap-and-dcapx-regulators?keyMatch=dcap2%20bode...
In the attached file you can see I have used both a bode plot block and a gain and phase margin plot block. In the bode plot block there are no errors while Gain & Phase margin block is showing error when I want to see bode plot...
