Inspect Generated Code for Nonvirtual Buses

This example shows how nonvirtual buses appear in the generated code for a model.

Open and simulate the example model, which contains a nonvirtual bus.

mdl = "NonvirtualBusCode";
open_system(mdl)
sim(mdl);

To generate code for the model, in the Simulink Toolstrip, on the Apps tab, in the Apps gallery, click Simulink Coder. On the C Code tab that opens, click Generate Code. Alternatively, press Ctrl+B or enter this command.

slbuild(mdl)

To see the generated files, open the NonvirtualBusCodeGenModel_grt_rtw folder.

NonvirtualBusCode_types.h defines the Simulink.Bus object as a structure.

typedef struct {
  real_T a;
  real_T b;
  real_T c;
} BusObject;

NonvirtualBusCode.h defines the Unit Delay block using the BusObject struct.

typedef struct {
  BusObject UnitDelay_DSTATE;          /* '<Root>/Unit Delay' */
} DW_NonvirtualBusCode_T;

NonvirtualBusCode.c implements the Unit Delay block, which passes the nonvirtual bus to the Outport block.

NonvirtualBusCode_Y.Out1 = NonvirtualBusCode_DW.UnitDelay_DSTATE;
