In another file, which is not generated from the model above, the following code

can be used to specify the parameter sets:

Calibratable parameter can be chosen by GetSet function that can be chosen for

any parameter or signal in the model. The tool for calibration can get access to the

parameter/signals in that way. ASAP2 files can be generated too.
