MATLAB: How to adjust the “Code Generation” pane in the simulink configuration parameters programmatically

code generationconfiguration parametersMATLABprogrammaticallys-functionsimulink

Hi everybody, I try to generate a Simulink S-Function programmatically. For this I have to adjust some properties in the Simulink configuration parameters from a MATLAB script. So far it is no problem, but I can not adjust the target specific options. I have to make sure that the "Code Generation->S-Function Target->Create new model" checkbox is enabled (see picture on left side). But this pane is not available, if I have changed the system target file before (see picture on rigth side). For example I have changed the system target file programmatically from "grt.tlc" to "rtwsfcn.tlc" and there is no "S-Function Target" pane. When I adjust it by hand, it works.

So how can I refresh the "Code Generation" pane after changing the system target file?

Thanks in advanced!!

(MATLAB R2015b)

I have found a solution myself.

The problem was that I have used the wrong function to adjust the system target file.

Wrong:

set_param('model_name', 'RTWSystemTargetFile', 'rtwsfcn.tlc');

Correct:

configSet = getActiveConfigSet('model_name');

switchTarget(configSet, 'rtwsfcn.tlc', []);

MATLAB: Setup BuildDirSuffix based on rtwoptions

Yes, there is a way to do this. You can set the tlcvariable field for the rtwoptions parameter. This field is basically the parameter that appears in the config set (and you get the parameter value by passing this field). To set the BuildSuffixDir, get the active config set and get the value of the required parameter. Refer to code below:

rtwoptions(myoption).prompt  = 'Version';
rtwoptions(myoption).type    = 'Popup';
rtwoptions(myoption).default = '1';
rtwoptions(myoption).popupstrings    = '1|2|3';
rtwoptions(myoption).tlcvariable  = 'versionValue';
%----------------------------------------%

% Configure RTW code generation settings %
%----------------------------------------%
cs = getActiveConfigSet(gcs);
tmp = cs.get_param('versionValue');
rtwgensettings.BuildDirSuffix = ['_mytarget' tmp '_rtw'];
rtwgensettings.Version = '1';

I believe making the above changes in tlc should fix your issue. Refer to this MATLAB Answer with a similar problem:- https://www.mathworks.com/matlabcentral/answers/98859-how-can-i-change-the-code-generation-directory-depending-on-my-selection-of-the-system-target-file-i

Also, you can also try using TLC Options parameter in configuration parameters - TLC Options

Hope this helps!

Make sure to select the System Target file as ert.tlc under code generation pane.
