How to use evalRequirement with decresing step?

Hi all,
I have a simscape model and I need to tune the parameters in order to match the desidered step response from a manunfacturer data. I use simulink design optimization to do this. I use evalRequirement function to see if the simulated step response match the desired one and it works perfectly with increasing step (i. e. when the final output is upper than the initial one). I noticed it doesn't work with descreasing step (i. e. when the final output is lower than the initial one), in other words when the simulating step response changes markedly, the output of evalRequirement doesn't and the highest violation is on the constraint of the final values. Does evalRequirement have few problems in evaluating the whether a signal satisfies specified bounds with decreasing steps? I have a feeling that evalRequirement doesn't work with decreasing step, since stepinfo doesn't work as well because it takes the max value of the signal so the overshoot is completely wrong. Any suggestion is appreciated
Thanks
Cheers
Pietro
