JTAG & Huntron Show New Test Methodologies
ProVision Designer Station software.
Eindhoven, Netherlands — Huntron, Inc. and JTAG Technologies are jointly presenting the integration of their test methodologies using Huntron's range of prober-enhanced analog signature analysis products.
The Huntron Tracker uses analog signature analysis in its PCB fault detection. But now users of this technology can take advantage of advances made in the digital world that allow PCBs to be tested using built-in logic circuits known as Boundary Scan or JTAG. This logic is built into ICs such as FPGAs, CPLDs DSPs, and microprocessors. The JTAG technology is commonplace on many of today's digital and mixed signal designs.
By equipping a Huntron system that utilizes the company's robotic probe technology with boundary-scan capability, it is possible to further enhance the test coverage achieved with these iconic test systems.
It works by synchronizing the stimulus/measurement probe of the Huntron with a boundary-scan test vector originally generated by JTAG Technologies equipment. An example of this would be in testing the continuity of a PCB track from a JTAG/boundary-scan compliant part to an edge connector. Without a sense probe on the edge connector, it would be impossible to detect an open circuit condition. The Huntron Robotic prober adds a low-cost and flexible way of performing this operation.
JTAG Technologies is also showing a new economically-priced software and hardware system for board-level and system designers. Boundary-scan testing has remained a powerful tool for identifying assembly faults such as open- and short-circuits, missing components and damaged devices since its introduction (as IEEE Std 1149.1) in 1990. However, while boundary-scan tools have been in use for almost 20 years, the relatively high cost of professional systems has meant that they largely remain in the domain of test and production engineers. This situation has changed.
JTAG Technologies' ProVision Designer Station now offers a low entry price yet retains key features such as automatic test program generation (ATPG) for interconnections and in-system programming (ISP) for devices. It is suitable for the preparation of all boundary-scan test routines that might be used in the design environment and beyond. The tool incorporates a highly automated test program generator for interconnects that takes advantage of a library of thousands of non-boundary-scan (cluster) device models to create a safe, high-quality core test.
The rapid generation and execution of this interconnect test using the JT 3705/USB controller (included with the system) allows the user to quickly determine that the core boundary-scan to boundary-scan pin connections of a design are defect-free.
