TetraMAX Small Delay Defect ATPG Boosts Test Quality at STMicroelectronics
STMicroelectronics was faced with the challenge of meeting very high corporate test quality objectives across all its product lines without increasing test costs. This challenge was made even more difficult since on-chip process variations are more pronounced in today’s manufacturing processes, resulting in more small delay defects (SDDs). Breakthrough timing-aware technology in TetraMAX automatic test pattern generation (ATPG) enabled designers at the company to use precise timing information generated by Synopsys’ PrimeTime static timing analysis, the industry’s defacto signoff solution, to quickly and easily generate patterns that target SDDs.

DFT strategy for ARM processor-based designs
This article provides an example of an optimized DFT architecture, referred to as “shared I/O.” It is enabled by Synopsys’ synthesis-based test solution, which has been used successfully in Samsung’s multicore processor designs. The experience demonstrates that shared I/O is a better approach than the standard DFT architecture for testing multicore designs since it reduces test costs by utilizing fewer pins while providing the same or better test time reduction.
