A friend of mine sent his simulation of a converter for which he had used PLECS. It is in the format "example.slx".
I have MATLAB R2017b. I downloaded the PLECS block set for MATLAB and activated it using the trial license. But when I try to open his simulation, I get an error saying that the source file was made in a newer version (2017b). The problem is that even I have the same version of MATLAB.
I tried to then load the file and convert it to its previous version (2016b). After this, I was able to open the slx file, but there was just a plain yellow PLECS subsystem which was empty inside. How do I access this simulation?
