Not able to run simulations using Rapid accelerator

Running the example provide by Mathworks to simulate in rapid accelerator (sldemo_bounce) I got the following error message:

to run the simulation in rapid accelerator do I need the real time workshop tools license?

No, rapid accelerator is different than real time workshop.

[Eduardo]

so, is only Simulink license required?

Any clue about the failed message when I try to run the simulation in rapid accelerator mode?

Hi Eduardo,

The “Rapid Accelerator” mode in Simulink, generates executable C files and in turn uses them to decrease the simulation time. It uses "gmake" command to generate the C files. Since the path to the target C file “C:/PROGRA~1/MATLAB/R2021a/rtw/c/src/rt_logging_simtarget.c” contains the special character "~", the command throws out an error.

Try simulating the model in another folder with no special character throughout the path. It would most likely resolve the issue.

You can refer the following MATLAB Answer that suggests the same:

Hope it helps.

The character ~ is not a problem in pathnames. It is the character used to compose "short path name" .
