Error creading HDL from subsystem

I changed the stateflow model of a state machine that I was previously able to generate HDL code for. I was using Matlab and Simulink 2010b the first time I generated HDL code for the state machine and I am now using 2011b. I now receive the following errors and warnings

Failure to init the model 'SPI_Controller' Error using initModel (line 33) Error due to multiple causes.

Any help is appreciated

Thank you

Do you happen to recall what changes you made to the model? I would also recommend reporting this to MathWorks Tech Support.

This is a model compilation issue and not HDL Code generation issue. Press ctrl-d or compile the model and make sure there are no errors before HDL code generation.
