Illegal data access or computation detected for the chart given that 'Execute At Initialization' must be enabled

Hi,

I am trying to generate hdl code for state flow chart and i enabled option "enable chart at entry" in properties. still i am getting error : Error: Evaluation of instantiation function on class hdlstateflow.StateflowHDLInstantiation failed with the error message: Error using ==> construct_error at 109 Illegal data access or computation detected for the chart given that 'Execute At Initialization' must be enabled. See above errors more information. Stateflow HDL code generation failed for chart 'Chart' (#247).

@shankar: The tag "urgent" is misplaced in a forum, in which volunteers create the answers in their sparetime. While I personally translate "urgent" to "did not manage to start in time", others are annoyed by this tag because they do not want to be pushed.

"Enable chart at entry" and "Execute at initialization" are two separate settings, both of which must be correctly set for HDL code generation.

The easiest way to ensure that any model is properly configured for HDL Coder is to use the hdlsetup command, like so:

>> hdlsetup my_model_name

This will set a number of parameters to suitable values for HDL code generation.
