How to use a workspace variable to modify a popup mask parameter?

I'm using the C2000 blockset for some power conversion applications. I have a simulink model that uses the C2000 ePWM block, and I would like to be able to change some of the popup parameters using the value of a workspace variable to support different hardware configurations. For example, I would like to change the "useModule" parameter using a workspace variable. How can I go about this?

Hi Evelyn,

I understand that you want to change the mask parameters of the C2000 ePWM block using a workspace variable.

It can be by importing the model into MATLAB script and setting the mask parameter by using the “set_param” function with a pre-defined workspace variable. You can refer to the below documentation to know more about the “set_param” function:

- Set Simulink parameter value - MATLAB set_param - MathWorks India

Here is a code snippet for the same:

% load the model in the script 
load_system('test'); 

% defining workspace variable 
hardware_config='ePWM8' 

% setting the parameter 'useModule' to the defined workspace variable 
set_param('test/ePWM','useModule',hardware_config) 

% getting the list all the mask parameters  
%get_param('test/ePWM','DialogParameters') 

Hope it helps,
