When you load an EDD binary into the DD IDE, and highlight the device or blocks on the left-side tree view, you should see several buttons labelled "create simulation file", "open simulation file", and "simulation off".
To create a simulation file, you would click on "create simulation file", and then to activate simulation, you would click on "simulation off", which should change the color to green, and then read "simulation on".
The “open simulation file” button can be used to open the simulation file if you want to modify any of the parameter values in it.
Below is a section of a simulation file for an Analog Input Block. Values saved in the simulation file will be reflected in the simulated device in the DD viewer.
