Using the AMESim MATLAB/Simulink InterfaceFigure 24: Actual input to the AMESim model using a sample interval of 0.001s.6. Using more than one interface blockMake sure you give each port a unique name.When the S-Function is created, AMESim will concatenateall the inputs and concatenate all the outputs. To see how thisis done, select Interface Display interface status. Adialog box (Figure 25) shows how the ports are arranged.24
MATLAB/Simulink interface 4.2User ManualFigure 25: Concatenated inputs and outputs.7. Concluding remarks and FAQs7.1. Concluding remarksThis manual has presented a simple example to introduce the use of the Simulink interface.Before you start developing your own models, we now summarize the most importantpoints:• If you work on a PC with Windows NT, Windows 2000 or Windows XP, you must useMicrosoft Visual C++ since it is the only compiler that can generate S-Functions forSimulink. The GNU gcc compiler supplied with AMESim cannot be used.• The input of the interface block in AMESim has its ports in reverse order comparedwith Simulink.• Remember to change from Parameters to Run mode in AMESim before running thesimulation in Simulink or to use File Write aux. files.• For systems using the standard Simulink interface the following points are important:• The AMESim model must be explicit i.e. there cannot be any implicit variables.The reason for this is that the Simulink integrators can handle only ordinarydifferential equations.• Users of previous versions of the AMESim-Simulink interface shouldnotice that the output dealing with discontinuities (Hit Crossing) has beenremoved.• For systems using the co-simulation interface it is important to think of the following:• Remember that the AMESim block is seen as a discrete block from Simulink.• The parameters to the S-Functions are as shown in the table in section 5.2.Usageof the co-simulation interface, and they are not the same as the parameters forthe standard interface.25
