The Software Design of NoC System Testing

According to the requirements of NoC fault detection, a technology combining the multiplex NoC communication architecture with boundary scan has been adopted to realize the design of the fault detection software for the NoC system. In this paper, the main testing objects are SRAM and combinational circuit of NoC. The fault models, whose faults occurred frequently, are researched. The March C+ and G-F algorithms, which are easy to implement and have high fault coverage, to obtain the test vectors and achieve fault test. The design has the advantages of the friendly man-machine interface, and is easy to use, and fault location can be realized with graphical method. Through testing on NoC platform, the results show that fault detection for the faults easy to occur in NoC system can be completed with the condition of the increase in few peripheral circuits,the intended functions have been achieved.
