An integrated framework to support remote IEEE 1149.1 /1149.4 design for test experiments

Remote experiments for academic purposes can only achieve their educational goals if an appropriate framework is able to provide a basic set of features, namely remote laboratory management, collaborative learning tools and content management and delivery. This paper presents a framework developed to support remote experiments in a design for test class offered to final year students at the Electrical and Computer Engineering degree at the University of Porto. The proposed solution combines a test language command interpreter and various virtual instruments (VIs), with a demonstration board that comprises a boundary-scan IEEE 1149.1 / 1149.4 test infrastructure. The experiments are presented as embedded learning objects, with no distinction from other e-learning contents (e.g. lessons, lecture notes, etc.)

IEEE Std 1149.7: What, Why, Where?

The IEEE Std 1149.7 holds the promise of greatimprovements for testing electronic circuits, when used alongwith other IEEE standards (particularly those that use the IEEEStd 1149.1 for test access and control). In this paper we describewhat is the IEEE Std 1149.7, the reasons why we mayconsider to use it instead of IEEE Std 1149.1, and we highlightthe application spectrum where this new standard can beuseful
