Improving yield of torus nocs through fault-diagnosis-and-repair of interconnect faults
Found in: On-Line Testing Symposium, IEEE International
By Caroline Concatto, Pedro Almeida, Fernanda Kastensmidt, Erika Cota, Marcelo Lubaszewski, Marcos Herve
Issue Date:June 2009
pp. 61-66
We propose a fault tolerance method for torus NoCs capable of increase the yield with minimal performance overhead. The proposed approach consists in detecting and diagnosing interconnect faults using BIST structures and activating alternative paths for th...
Diagnosis of interconnect shorts in mesh NoCs
Found in: Networks-on-Chip, International Symposium on
By Marcos Herve, Erika Cota, Fernanda Lima Kastensmidt, Marcelo Lubaszewski
Issue Date:May 2009
pp. 256-265
We propose a method to diagnose interconnect short-circuit faults in mesh 7oCs. The fault model comprises all shorts between any two wires of a defined 7oC neighborhood. Test sequences are applied in 7oC functional mode. Experimental results show that 93% ...
