HP94000 multi-site mixed signal test development considerations
S. Jannesari · 2003
This paper describes the implementation of a quad site test solution on HP94000 Mixed Signal LSI Test system. The HP94K has multi site test capability meaning that, multiple components can be tested simultaneously in parallel provided there is enough test resources in the system. It also has the capability of parallel processing. With parallel processing capability, one can perform complex computations on previously collected data while new data in being collected into the capture memory therefore reducing test time. The test solution described in this paper is for Burr-Brown's ADSI20I high dynamic range delta sigma modulator. Circuit design and layout considerations are paramount when considering a mixed signal multi site test solution on HP94K. The test solution must go through a vigorous capability study, to verify test repeatability not only on a single site basis but also between site to site.
