The AutoBuzz Tool employs a seek-and-discover technique to scan a compliant design and perform comparative tests using JTAG/boundary-scan. With only JTAG scan-chain information plus BSDL models of the JTAG/IEEE 1149.1-compliant parts, users can connect to their designs via a number of compatible JTAG interface options. AutoBuzz supports two operating modes: learn and compare. In learn mode, a known-good sample PCB is scanned to establish a reference connectivity map. Suspected faulty boards then can be scanned in compare mode, and a comparison is automatically made of their connectivity maps.
