How to reset a subsystem with trigger type "function call" in unit test?

Hello everyone,

just I need to do an unit test for a subsystem with stateflow-charts. I have generated a test harness (test sequence) and tried to add some test cases.

However, I found I could not reset the subsystem. After running some test cases, the subsystem could not go back to initialization.

The subsystem has a trigger with following setting:

Trigger type: function-call; States when enabling: held; Propagate sizes of variable-size signals: During execution; Sample time type: triggered

This subsystem comes from a customer. Therefore, I hope that I don't need to change any thing in this subsystem.

A function-call scheduler was generated with send(trigger) automatically.

My question is:

how to reset the subsystem for each test case? I would like to know solutions for "test sequence" and "signal builder".

Thanks for your attention!

Best regards, XiC

If the "function-call" subsystem is driven by the stateflow chart, have you tried wrapping it inside a resettable subsystem?
