With the growing size of modern designs and more strict time-to-market constraints, design errors unavoidably escape pre-silicon verification and reside in silicon prototypes. As a result, silicon debug has become a necessary step in the digital integrated circuit design flow. Although embedded hardware blocks, such as scan chains and trace buffers, provide a means to acquire data of internal signals...
With the growing size of modern designs and more strict time-to-market constraints, design errors can unavoidably escape pre-silicon verification and reside in silicon prototypes. Due to those errors and faults in the fabrication process, silicon debug has become a necessary step in the digital integrated circuit design flow. Embedded hardware blocks, such as scan chains and trace buffers, provide...
Since pre-silicon functional verification is insufficient to detect all design errors, re-spins are often needed due to malfunctions that escape into the silicon. This paper presents an automated software solution to analyze the data collected during silicon debug. The proposed methodology analyzes the test sequences to detect suspects in both the spatial and the temporal domain. A set of software...
