JTAG Visualizer is an advanced graphical viewer and data management system for PCB schematics and layouts. Visualizer integrates seamlessly with the JTAG Technologies family of boundary-scan products, such as the ProVision application development platform, and accepts PCB data from a variety of CAD, CAM and EDA tools. In design Visualizer provides DfT (design for test) feedback to the user by enabling a graphical view of fault coverage on their design. In manufacture and test Visualizer can be used to highlight faulty nets (short circuits, opens, stuck-ats etc.) in both layout and schematics views.
