problem about powergui in simulink

hi.....i am doing simulation of H-bridge inverter. i want to analyze FFT by using powergui block in my simulink model.if i open the powergui block and try to do FFT analysis then it shows empty in the available signal section.

any help please...

Are there any errors/warnings displayed in the MATLAB command window?

My speculation would be that the powergui block is being treated as a physical signal, and so is not available as a signal in the main Simulink.

See for example the similar sort of problem over here

Hi Guy on Simulink (Walter) i follow your blog, and that's why i ask you for help, because you work with phisycal modelling, please refer to this link to understand my doubts about SPS, http://es.mathworks.com/matlabcentral/answers/315484-is-it-possible-a-buck-converter-in-discrete-time-not-in-continuos-solver Thanks in advance!.

I do not have a blog. I have never discussed Simulink on social media either. I do not know enough about Simulink to answer your question.
