Routing Design for Test Scheduling of 3D NoC Based Bandwidth Division Multiplexing and Multi-Clock

Routing strategy is designed in this paper to solve the problem of 3D NoC test Scheduling based Bandwidth Division Multiplexing and Multi-Clock efficiently. The format of data packet is designed based on the characteristics of 3D NoC, the XYZ routing strategy with multicast technology is used, and the resource collision waiting mechanism is designed in this paper. We take the circuit in international standard test set ITC'02 as the experimental object, under the dual constraint of power consumption and bandwidth, the test scheduling of 3D NoC based improved particle swarm optimization (PSO) algorithm with bandwidth division multiplexing and multi-clock strategy is used to verify the correctness and effectiveness of the routing we designed.
