hello! The option of "Load from workspace => Initial state" is used to let simulation start from last time. But I find that it only acts on the inherent blocks of simulink, such as the initial voltage of the capacitor, while no effects on s-function. The s-function still use the values given in "mdlInitializeConditions()". How can I let it use the values in "Initial state"? Thank you!

POWERGUI can only specify initial states for the inductors and the capacitors of the circuit. The initial states for IGBTs and the Diodes cannot be set. To work around this issue, use the "Load from Workspace the initial states" feature of Simulink.
Instructions:
1. Open model
2. From the "Workspace I/O" tab within the Simulation parameters dialog box, put a check next to "Save to workspace: Final State". The "xFinal" vector will contain the final states of the simulation.
3. Simulate model until it reaches the desired steady-state condition.
4. Uncheck "Save to workspace: Final State".
5. Check "Load from workspace: Initial State" and specify "xFinal" as the initial vector.
5. Run the simulation. It should start in the steady-state condition.
The initial conditions set by the POWERGUI have no effect when the"Load from Workspace the initial states" option is checked.
It's also possible to use a junction: connect the default transition to a junction (a circle) and from that junction, have transition to the different possible initial state with conditions on these transition. (be sure to have one valid path to a default state in all cases)
