Teradyne SPECTRUM Boundary Scan Integration System Description:
Limited access testing using IEEE1149.1 standard is now an essential part of manufacturing test strategy for complex and high node count digital boards. Teradyne SPECTRUM series of In-Circuit testers provide Boundary Scan capabilities. The SPECTRUM delivers the test patterns through the system Channel Cards (driver/receiver) and uses VICTORY for test pattern generation and diagnostics. The 8800-series In-Circuit machines provide BICT type of device level testing as well as Virtual Interconnect (VIT) and Cluster (VCCT) testing.
Spectrum’s ILDP feature enables the tester for in-system programming of Flash and other programmable devices, using the parallel access through its Channel Cards. The data delivery rate of the system is up-to 5MHz on the standard CC2 cards, and the higher end system mainframes can be equipped with higher speed cards. The SPECTRUM 8800 series, like most In-Circuit testers, is designed for parallel access and parallel pattern delivery. Even though the systems can deliver boundary scan serial patterns to the DUT, performance and throughput is not desirable for complex operations such as on-board device programming. The integration of a stand-alone Boundary Scan controller with the Teradyne 8800-series can enhance the system’s capability and provide access to additional tools. The integration strategy provides the user with a common platform and portability of test patterns from stand-alone to ICT and later-on to functional test and depot test station.
The ChallengeSeamless integration of stand-alone Boundary San tools (BST) with Teradyne S8800-series has posed a challenge to many BST suppliers in the past, due to long distance between the ICT test fixture and the BST controller in the PC.
Acculogic’s Solution
Acculogic proven and patented Adaptive Clocking™ technology completely eliminates the effects of the long distance between the BST controller and the ICT test fixture therefore removing the hardware obstacle to seamless integration of Acculogic Boundary Scan tools with all S8800- series platforms. Acculogic BST systems can be fully integrated with the Teradyne 8800-series of testers.
