System Level LBIST Implementation
Fei Zhuang, Junbo Jia, Xiangfeng Li · 2008
In industry, chips become more and more complicated as advancing in deep submicron silicon process technology. LBIST can cover some newly emerging faults missed by traditional ATPG. That's why LBIST is becoming more and more popular. Besides launching LBIST through TAP interface, CPU launch LBIST feature may provide more flexibility for system-level or product testing and debugging. System engineer can easily kick-off LBIST with CPU interface instead of TAP.
