error in Simulink simulation time

I simulate a model in Simulink with a discrete solver, the result of simulation is limited to a reduced interval e6 à10e6 even if I set the simulation time from 0 to 10e6, what is the parameter to change to remedy

1 - Block-dependent settings:

Check if any of your blocks have an explicit sample time that is too small, by going to Display --> Sample Time --> All and looking at the colors/labels.

2 - Global model settings:

Go to your Configuration Parameters (Ctrl+E). In the Solver pane, see if you have set your Max step-size (or if fixed-step, your regular step-size) to this small number.

Thank's for your replay, i try it but the problem still subsite,

[Sebastian Castro]

Well, if you have any other information besides "still doesn't work", let me know and I can give you some more ideas :)

[studentU]

thank you ,

may be that the Y axis is fixed to a small step, so how can I not for this axis?

[Sebastian Castro]

You mean the X axis (time)?

Are you using a Scope or are you outputting the data into the MATLAB Workspace?

[studentU]

the Y axis, i use Scope.

[Sebastian Castro]

If it's the Y-axis, you can just right-click the scope axes and you will get 2 important options:

1. Axes properties: Lets you manually enter values for Y-min and Y-max, depending on how you want your plot to look.
2. Autoscale: It will scale the Y-axis automatically to fit all the data

There is also an "Autoscale" button on the scope toolbar. It should look like a square with 4 arrows pointing out at the corners.
