In hierarchical DFT efforts, all implementation, including pattern generation and verification, is done at the core level, which presents some challenges. To test a group of cores concurrently using a ...

Harrison: We introduced our SSN (Streaming Scan Network) product back in 2020. It laid the foundation for test pattern delivery and optimization, and at the time, it was a significant step forward for ...

This paper describes the detailed aspects of hierarchical DFT, with Shared Scan-in methodology using DFTMAX, the low pin count solution from Synopsys. The technique of sharing scan-in data between ...

At times physical design engineers find it difficult to relate with the additional timing modes introduced in PnR due to DFT insertion. These additional timing modes and related issues could be ...
