A design-for-debug (DfD) architecture can include, for an IC with on-chip memory, a debug module connected to a functional bus of the IC. The debug module receives trace data for an interval, generates compact signatures based on the received data, and compares these signatures to expected signatures. Intervals containing erroneous trace data can be identified by the debug module and stored in on-chip memory. A single iteration of signal tracing for debug testing between automated test equipment and the IC is possible."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal tracing using on-chip memory for in-system post-fabrication debug","description":"A post-fabrication debug and on-line error checking framework for 2D- and 3D-ICs with integrated memories is described.
