Yield and performance enhancement through redundancy in VLSI and WSI multiprocessor systems

I. Koren, D.K. Pradhan
1986 Proceedings of the IEEE  
In the second part of the paper we discuss models that evaluate how yield enhancement and reliability improvement may be achieved by certain fault-tolerant techniques. I .  ...  Concerns about fault tolerance in VLSI-based systems stem from the two key factors of reliability and yield enhancements. Low yield is a problem of increasing significance as circuit density grows.  ...  However, this would require giving up the use of seven good nodes. Alternatively, one can partition the 4-cube into 4 subnetworks of 2-cubes.  ...
