The paper describes a new approach of boundary scan emulation based testing for adaptive failure diagnostics using programmable logic. The motivation to speed up boundary scan based testing as well as the approach taken for this new concept and architecture are presented. With this approach the possibilities of boundary scan testing can be extended by using the available on-board resources for a faster and more real-time oriented test. The new options and benefits, as well as the necessary fundamentals of this approach are indicated. An example and first test results are given as well, to indicate the advantage of the proposed system. Keywords: adaptive systems; automatic test equipment; boundary scan testing; field programmable gate arraysI.
