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.
