Abstract An apparatus and method for generating distributed traffic in nodes coupled to a bus, wherein one node reads information on other nodes and generates traffic, includes a bus interface unit and a control unit receiving signals. The signals are transmitted from the nodes via the bus interface unit, to detect a bus reset and determine the number N of nodes coupled to the bus and a node ID number K of a node having the control unit. The information on the nodes is read in a predetermined order, starting from a reference node with node ID number K+M, wherein M is an integer larger than 1−K and smaller than N−K. The apparatus controls the order of generation of read transactions in each node for reading information from the other nodes coupled to a bus. The traffic load applied to each node is distributed to reduce an initial bus stabilization time.
