USING AN ELEMENT IN A FIRST MODEL TO CALL A PORTION OF A SECOND MODEL

A method comprises generating code for a caller element of a first graphical model and a called element of a second graphical model, comprising: generating a first function representing an interface between the caller element and the called element, through which the caller element calls the called element, the first function comprising: first input arguments corresponding to input variables of the caller element, and first output arguments corresponding to output variables of the caller element, the called element comprising the input variables and the output variables passed from the caller element, and generating a second function representing an underlying function of the called element, the underlying function including the input variables passed from the caller element, the output variables, internal input variables and internal output variables, the second function comprising: second input arguments corresponding to the the input variables and the internal input variables, and second output arguments corresponding to the the output variables and the internal output variables.
