I have trained network model in simulink, I am trying to perform GPU acceleration.
But, I am gettin the following error:
Value 'sm_86' is not defined for option 'gpu-architecture'
I have dowloaded cuda. Still, the error doesn't go

Which version of MATLAB are you using? I believe installing CUDA won't substitute for the version MATLAB is using unless you force it to. So presumably you are using a CUDA 10 version of MATLAB (R2020b or earlier)?
Edit: I see that CUDA 11.0 doesn't support compiling for cc8.6, so no released version of MATLAB will work. It seems you need support from the Coder team to determine how to prevent cc8.6 arch being used in the compiler options or alternatively to force Simulink to use your installed version of CUDA instead of the shipping version.

@Joss Knight According to the Release information they entered, R2021b.
