Scan Pathfinder is an optional software feature available for TestStation as a Diagnostic License and a Program Prep License. The Scan Path Test Diagnostic license allows users to run boundary scan test programs on the tester hardware and use the specialized Scan Pathfinder diagnostic software. The Scan Pathfinder program prep license is designed to automatically generate and execute comprehensive tests of boards that have boundary scan components and limited tester access. Scan Pathfinder analyzes the board circuit description and BSDL models to determine the scan path configuration and automatically generates a boundary scan test program and diagnostic file. Scan Pathfinder does not require tester nail access to detect targeted faults on the boundary scan nets, therefore it is primarily intended for test situations where the tester will not have access to the boundary scan device pins. Both Scan Pathfinder Diagnostic and Program Prep license include BasicSCAN.

Key Features

• A graphical, mouse-based, workspace that simplifies selection of test options and viewing of boundary scan test reports
• Support for boards with multiple scan paths
• Automatically generates boundary scan test programs based on detected scan path configuration
• Automatically isolates boundary scan devices while executing the conventional in-circuit tests
• Hardware Test verifies the integrity of the component boundary scan test circuitry
• Opens Test diagnoses open pin faults on boundary scan pins that have access to a tester nail
• Interactions Test diagnoses shorts between conventional nodes that have access to a tester nail and boundary scan nets that do not have access to a tester nail
• Interconnect Test diagnoses opens and shorts on boundary scan nets that do not have tester nail access
• RunBIST Test performs parallel device logic testing of all boundary scan components that support the optional RunBIST instruction
• Virtual Digital Test feature allows testing of non-nailed conventional digital component pins using boundary scan pins as virtual drivers and sensors
• Comprehensive test reports that can be viewed in graphical report summary windows or as text files
• Comprehensive Boundary Scan Run Time Diagnostic task ensures accurate device and pin level diagnostic messages
