Why do I get an error when using a SimPowerSystem model as a model reference in MATLAB R2014a?

When I try to use a SimPowerSystem model as a model reference in MATLAB R2014a I get the following error:

error using ==> RTW.makertw.make_rtw 

Error using ==> tlc_c 

Error using ==> rtwgen 

Error using ==> set_param 

Model reference does not support non-inlined S-Functions.  The S-Function 'sfun_spssw_contc' used in 'ActuatorModel_Final/powergui/EquivalentModel1/State-Space' is not inlined.  To be able to reference the model 'ActuatorModel_Final', the S-function needs a target file (sfun_spssw_contc.tlc) and the option SS_OPTION_USE_TLC_WITH_ACCELERATOR must be set in the S-function source code.

Why am I getting this error?

This is a known limitation in MATLAB R2014a.  The S-Functions of SimPowerSystem simulation are not inlined. Consequently you get an error when you try to build code for model reference.
