XJTAG DFT Assistant for Mentor Xpedition


Cambridge, UK — Developed by XJTAG®, DFT Assistant for Mentor® Xpedition® is designed to significant- ly increase the design for test (DFT) process and debug capabilities of Xpedition’s schematic capture and PCB design environment. PCBs are increasingly


densely populated and access to pins under many pack- ages, such as BGAs, is basi- cally impossible. JTAG was designed to solve the problem of access, but it is vitally im- portant to get the JTAG chain correct at the design stage. Failure to identify and fix design errors at an early stage can result in board re- spins and costly product de- lays. DFT Assistant helps to validate correct JTAG chain connectivity, through full in- tegration with the Xpedition schemat- ic capture environment. The XJTAG DFT Assistant

comprises two key elements: the XJTAG chain checker, and the XJTAG access viewer. The chain checker identifies common errors in a JTAG scan chain, such as incorrectly connected test access ports (TAPs). A single connection error would inhibit an entire scan chain from working. XJTAG chain checker identifies con- nection errors and reports them to the developer during the design process. Incorrectly terminated TAPs are also identified. XJTAG access viewer overlays the extent of boundary scan access


onto the schematic diagram, allowing users to see which components are accessible using boundary scan, and where test coverage could be further extended. Engineers can highlight the nets individually to show read, write, power/ground and the nets

that do not have any JTAG access on the schematic. While the first prototype is being


manufactured, DFT Assistant allows engineers to export a preliminary XJTAG project from the Xpedition schematic capture environment to the XJTAG development software, where additional tests can be developed. These can then be used to test real


hardware, as soon as it is available. Contact: XJTAG, St. John’s In- novation Centre, Cowley Road,
