Abstract

System-on-Chip designs use numerous and diverseembedded cores and memories. V ery high system reliability requirements mandate greater than 99.9% ATPGchip manufacturing test coverage. Logic BIST andMemory BIST are increasingly used for high systemtest coverage with additional constraints that somecores or pockets of user designed logic have to be functionally active during BIST. This paper will describethe challenges of a design methodology to handle suchSOC designs and the automated solutions that addressthese problems.
