Hi @jason yeh,

To ensure that the value in the constant block gets updated simultaneously when you change the workspace variable, we can use the "set_param" function to update the model. Please see the below command which gives an example of the function usage.

set_param(model,'SimulationCommand','Update')

You can either run this command in the command window or use this command in the model callbacks to ensure that the model is updated whenever necessary. We can use the "InitFcn" callback in "Modelling > Model Properties > Callbacks" to update the value before simulation starts as shown below.

For more information on the "set_param" function, please use the below command.
