Analyze Boundary-Scan Coverage

Boundary-scan coverage analysis requires importing schematic data, netlists, and Boundary Scan Description Language (BSDL) files into a design-for-testability (DFT) analysis workflow. The process evaluates node connectivity, validates boundary-scan chain configuration, and classifies coverage conditions including full coverage, shorts-only coverage, open-only coverage, drive-only coverage, and partial coverage across printed circuit board assemblies.

The design-for-testability workflow analyzes connections between boundary-scan and non-boundary-scan devices, identifies signal integrity concerns caused by fan-out conditions, and generates node-level reporting for manufacturing test review. Coverage reports provide detailed visibility into interconnect behavior, connector testing, pull-up and pull-down analysis, and defect detection classification to support production test development for complex digital systems.

Boundary-Scan Coverage Solution

Boundary-scan coverage analysis requires automated evaluation of node connectivity, defect detection classification, and design-for-testability reporting across complex printed circuit board assemblies. The solution provides comprehensive design-for-testability analysis and reporting capabilities that evaluate node behavior, identify fault coverage capabilities, and deliver clear visibility into boundary-scan connectivity across complex board designs.

The solution uses the Keysight boundary scan analyzer with software to import schematic data, netlists, and BSDL files for boundary-scan verification and analysis. The software verifies boundary scan implementation, evaluates compliance pin configuration, and identifies potential signal integrity concerns caused by fan-out conditions. It also provides node-level visibility into connectivity, interconnect behavior, and fault analysis results, enabling faster analysis and troubleshooting of complex printed circuit board design.
