It will be instantiated like any other component. As you showed, the module interface signals have self explanatory names.

The models internal data array will be available for inspection and forcing as well.

Furthermore, you should check whether some port will be tied with "1" or "0" for this model!

Thank you. I can now read data from a preload flash. However, the page-program command still does not work...

However, the page-program command still does not work...

The good point with a simulation model is, you can inspect the internal state machine and determine why.

you can check whether this model support page-program command?
