I am try to build PIL test, but a problem appears,so if anyone else can solve the event,please tell me .Thanks!

An error occurred while creating an instance of connectivity configuration class "tic2000codertargetpil.ConnectivityConfig". Check that this is a valid connectivity configuration class.
Caused by:
MATLAB Serial PIL preferences (MathWorks_Embedded_IDE_Link_PIL_Preferences) are not configured properly. Please set the preferences as explained in: Choose a Serial Communication Interface for PIL Simulation
Component:Simulink | Category:Block diagram error

It is telling you that you need to configure a COM port in the Serial PIL preferences.
