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.

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.
