A behavior analyzer for real-time and multiprocessor applications

Testing and debugging are of the most dmcult steps in the design of real-time applications. This problem arisesfrom the difJiculty to reproduce the application behavior which leads to an error. To overcome this problem, a behavioral description model and graphical tools which exploit it are presented in this paper. They enable a first analysis of the application behavior before any application run in order to assess the hardware architecture choice. They can also be used during the application execution to gather neequl information for debug. These information are then ured by graphical tools to display the application functional behavior.
