Why am I unable to create a model reference from a model that contains blocks from the SimPowerSystems blockset in SimPowerSystems 5.2 (R2009b)?

I have a model that contains blocks from the SimPowerSystems blockset. I would like to use that model as a model reference in another model. However, this is not possible since the S-functions in SimPowerSystems are not inlined. Consequently, I obtain an error when I attempt to build code for model reference:

 Error using ==> rtwgen

 Cannot generate reusable model reference target for model spstest. The S-Function block 'spstest/powergui/EquivalentModel1/State-Space' does not support code reuse. The block (a) should have a TLC implementation (b) should set the option ''SS_OPTION_USE_TLC_WITH_ACCELERATOR' and (c) should set the option 'SS_OPTION_WORKS_WITH_CODE_REUSE'.

Alternatively, you can update the "Total number of instances allowed per top model" parameter, in the 'Model Referencing' page of the Configuration Parameters dialog, to "One".

The ability to simulate a referenced model in "Accelerator" or "Rapid Accelerator" mode is not available with SimPowerSystems.

To work around this issue, always simulate referenced models in "Normal" mode.
