how to get simulink stop time even if using code generation

I am trying to generate a chirp signal that is dependant on the simulation stop time(currently is set to 1 second). I do have matlab programming in the simulation so I keep running into an issue with "code generation" that won't let me do it. i've tried get_param as well as a couple other different tricks to be met with little to no progress.

Not sure what you mean.

>> vdp
>> get_param('vdp','StopTime')
ans =
    '20'

I get 'get_param' is not supported for code generation.

Yes. Imagine that after the code is generated and compiled and is running in a CPU, there would be no "model" and no "stop time".
