Zero crossing detection with level-2 M s-functions

I know that level-2 M s-functions do not support Zero-crossing detection. Do you know if there is a work-around procedure in order to be able to do that anyway? For instance, by means of a specific external block that reads an s-function output... I don't know.

Thank you very much.

Interesting question. Try using the Hit Crossing block at the output and check the "Enable zero-crossing detection" box on its dialog. Does that do the job for you?
