A novel approach to integrating Boundary Scan with other board-level ATE

This article introduces a novel approach for the integration of JTAG/Boundary Scan tools with other Automated Test Equipment. Previous technologies typically stopped short of being really integrated by just executing the same stand-alone Boundary Scan test vectors on a third party ATE, instead of combining resources of both the JTAG tool set and the third party ATE. HySCAN, the method introduced in this article, takes advantage of abstract test resource definitions, allowing the same set of Boundary Scan test vectors to be executed on various ATE equipment, utilizing ATE test resources to extend the test coverage compared to standalone Boundary Scan, without the need of adapting the Boundary Scan test pattern.
