Tom Thompson at Freescale recently wrote about our new Runner-Lite for QorIQ release. Our relationship with Freescale enabled us to quickly integrate support for Freescale probes into Runner-Lite, enabled test access with the same Codewarrior TAP probe used for board bring-up and software debug.
Tom makes a great point: there is huge value in testing hardware prototypes—especially processor-based embedded systems used for software development—as early as possible in the product life-cycle. We’ve consistently heard from users of both boundary-scan and JTAG Embedded Test (JET) tools about how important it is to know prototype hardware was built correctly to avoid the inevitable uncertainty when hardware problems creep up during software development.
That’s the advantage of JTAG-based test: the same structural and functional hardware tests used for volume manufacturing can be applied to products at all parts of the product life cycle, providing assurance during critical development phases.
