ABS latency analysis is difficult issue in design phase. In this article the causes of each system delay is analysed and end to end flow delay algorithm in the worst case is used, Architecture Analysis and Design Language(AADL) is studied to model the system. End to end flow latency has been computed and compared with the expected value by AADL tool OSATE. The result shows that the analysis method can be used to resolve the flow latency bottleneck and it provides a new approach to system design and optimization.
