Running Simulink in rapid acceleration mode

Hi. I am trying to run a simulink model in rapid accelerator mode without any success. It says the rapid accelerator target for model is successfully built but it still returns an error. The simulink model uses a number of S-Functions and called from a matlab script using the 'sim' function. Here is the error I get:

### Building the rapid accelerator target for model: R_MOD

### Successfully built the rapid accelerator target for model: R_MOD

Error using rapid_accel_target_utils

Error occurred while simulating the model 'R_MOD' in rapid accelerator mode. Rerun the simulation in normal mode to

diagnose this error.

Error in rapid_accel_target_utils

Error in sl (line 15)

[varargout{1:nargout}]=feval(varargin{:});

Please any idea(s) on how I can progress?

Have you tried to "Rerun the simulation in normal mode to diagnose this error."? Does it give a different error message?

Jonas, the simulation runs perfectly in normal mode as well as accelerator mode. An additional info: rapid_accel_target_utils is a file in the matlab private folder with a .p extension (rapid_accel_target_utils.p)

Hi,

I have found the same issue. Model with mex function works perfectly for normal, accelerator and rapid accelerator mode. But if I call the model programmatically from Matlab like:

sim('mdl.slx', 'SimulationMode','rapid');

Then I get the error:

Error occurred while simulating the model 'mdl' in rapid accelerator mode. Rerun the simulation in normal mode to diagnose this error.

So again, when I click on green arrow (Run) in simulink it works fine in rapid accelerator mode, when I call it programmatically as above, it failed.

I have no idea what could be possibly wrong :/

Hi @Eyefujirin Ejegi,

I encountered a similar issue with Rapid Accelerator mode and upon doing some research I found the following bug reports on the same:

1. https://www.mathworks.com/support/bugreports/3061276?s_tid=srchtitle_support_results_2_fails%2520Rapid%2520Accelerator%2520Simulation%2520mode.

Updating my MATLAB version resolved the problem for me, and you might find success by trying the same.

I hope this helps!
