Develop the following FlexRayT M cluster: The cluster consists of the 5 nodes A, B, C, D and E. All nodes should be connected via two channels. The cluster uses a bus topology. The nodes A, B and C are executing a safety critical task and therefore their bus requests should be guaranteed at the time of 20 macroticks. The following is expected from you:

 

·         Download the levi FlexRay simulator [Sirocic and Marwedel, 2007a]. Unpack the .zip file and install!

·         Start the training module by executing the file leviFRP.jar.

·         Design the described FlexRay cluster within the training module.

·         Configure the communication cycle such that the nodes A, B and C have a guaranteed bus access within a maximal delay of 20 macroticks. The nodes D and E should use only the dynamic segment

·         Configure the node bus requests. The node A sends a message every cycle. The nodes B and C send a message every second cycle. The node D sends a message of the length of 2 minislots every cycle and the node E sends every second cycle a message of the length of 2 minislots.

·         Start the visualization and check if the bus requests of the nodes A, B and C are guaranteed.

·         Swap the positions of nodes D and E in the dynamic segment. What is the resulting behavior?
