When simulating a System Generator design in Simulink, if I change the Simulink simulation mode
to "Accelerator", the simulation does not work and fails with errors.
Is this flow supported?
No, the "Accelerator" simulation mode is not supported and is not compatible with System Generator.
You will need to set the simulation mode to "Normal" to get your simulation to work.
As a possible workaround to speed up your simulation, you may wish to consider performing
Hardware in the Loop simulation. This flow can considerably speed up simulation run-times.
More information on this flow is available in the System Generator User Guide:
