How can I find out the subsystem computation time for each tilmestep?

Hi all,

At the moment I am working inside Simulink, trying to simulate a real-time applicable control scheme. The entire simulation runs about 3-5x faster than the time over which is simulated.

However as at some instances the computational time required will be longer than at some other time instance. For my real-time application it is necessary that all these individual computational steps take less than a certain amount of time. Is it possible to find out how long a subsystem block takes to compute a step?

I was looking at the 'tic/toc' functions but don't clearly see how I should/could implement this... Or is there maybe another function/block for this? The solver profiler tool only shows me how large each step taken was, but not the time it took to compute this step.

I hope you guys can help me!

Kind regards,

Bram

Use Simulation profiler (not Solver profiler) to check profile info of blocks in the model.

Thanks TAB, I have found the Simulation Profiler.

However I still can only find an average computation time, while trying to localise peak performances. Is it possible to identify the time required for each individual call?

Kind regards,
