Cooperative Built-In Self-Testing and Self-Diagnosis of NoC Bisynchronous Channels
This paper proposes a built-in self-test/self-diagnosis
procedure at start-up of an on-chip network (NoC) for bisynchronous
communication channels. Concurrent BIST operations
are carried out after reset at each switch, thus resulting in
scalable test application time with network size. The key principle
consists of exploiting the inherent structural redundancy of the
NoC architecture in a cooperative way for the effective diagnosis
and error detection. At-speed testing of stuck-at faults can be
performed in less than 4000 cycles regardless of their size, with
an hardware overhead of less than 30%
