Simulink: How to start simulation of a subsystem separately?

Hi guys,
I would like to start simulating an enabled or trigger subsystem separately. Right now when I run the simulation, the subsystem starts simulating as well. To be more specific, I have a step in my subsystem that starts at 1 for 3 seconds and then goes to 0. When I trigger this at t=2, I only get 1 for another second instead of 3 seconds as I intended and then it drops back to 0.
How to I solve this?
Thanks in advance

If your subsystem is inside an enabled subsystem, you simply have to disable the Enabled Subsystem until t=2.

The control signal of the enabled subsystem is used to enable/disable the subsystem. You need to use an appropriate combination of blocks to generate a signal that is 0 when the subsystem needs to be disabled and 1 otherwise.

The Step block uses the time from the model, you cannot offset it. Typically, to do what you are looking for you will need to implement your own source using blocks that are not function of the simulation time.
Usually, a combination of Sum, Gain, Switch, Integrator, etc can allow you to build many simple signals.
