The set of the code of Elementary Function, by splicing different component models, combination, relevant parameter being arranged, so that it may as taking product
Wood equally builds a system model.Later, under orderly standard operation, system model can be translated into and can run
Simulation code.
One system model is needed comprising different component models, while a component model also can be contained in difference
System model in, this provides condition for the multiplexing (i.e. the recycling of code) of component.Using model as the performance of system
Mode not only intuitively, but also is also used as showing the carrier of information when system operation, this is conducive in System Integration Test
