A few basic Simulink/Simscape questions

In the past I've generally used Simulink simulations for short bursts of transient analysis.

I was curious if it were possible to use it more like LabView, where a simulation can also run forever (tstop = inf), and you can interact with and modify the setup in run time by pushing buttons (opening and closing SimScape circuits).

Regarding memory, I would not want to store all time data. It would be good to store the trailing 10000 points. I'm not sure how to do that either.

Here is something I just threw together that does what I think I need. Not sure how to handle the memory though. If there are a lot of measurements, the memory would fill pretty quickly.

run forever (tstop = inf)

Yes. Set the simulation stop time to be inf

store the trailing 10000 points

Yes. Limit the data points of Scope or data logging.

interact with and modify the setup in run time by pushing buttons

Yes with limited capability. Certain block parameters can be changed while the simulation is running and it will take effect right after change.

If I limit the data points on the scope, does that just limit what is displayed? Is memory filling up anyway?

[Fangjun Jiang]

I don't think the memory will be filling up. Otherwise, it does not make sense. I've been running some simulation for a very long long time.
