Method for testing delay attribute of embedded system stream based on model

The invention discloses a method for testing a delay attribute of an embedded system stream based on a model, which is characterized by comprising the steps of: building an AADL (Architecture Analysis and Design Language) model simulation test platform based on a System C hardware description language, converting an AADL model into a system example executed by the test platform, abstracting and mapping a member sequence and a port sequence during the convection, converting a stream in the AADL model into a test model described by C++, completing the test of the delay attribute of the AADL stream in a process of executing the simulation of the system example, and analyzing and estimating a test result. The method can be used for dynamically testing the delay attribute of the stream of the AADL model in the design stage of the model, and iteratively constructing and fining the design model according to the test result, thereby being convenient for finding the problem in the design modeland improving the development efficiency of the design early stage of the AADL model.
