Free software speeds test, debug in pcb design environment

XJTAG Free software for the Mentor Xpedition Designer product increases the design for test and debug capabilities of the schematic capture and printed circuit boards (pcb) design environment. Product is comprised of two key elements: XJTAG Chain Checker and XJTAG Access Viewer. XJTAG 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 connection errors and reports them to the developer during the design process. Incorrectly terminated TAPs are also identified.
