Investigations of mixed-signal circuits equipped with innovative test bus
M. Borkowska, R. Gonera · 2003
The subject of the investigation was the efficiency of diagnostics by means of the IEEE Std. P1149.4 mixed-signal test bus. The novelty is the possibility to test analog part of circuits which is achieved thanks to the analog lines and the analog modules of the bus. Correctness of probes created by digital and analog boundary modules of the bus was checked. Interconnections, the presence and value of discrete components and integrated circuits were investigated in the models equipped with the test bus. The results of works aimed at evaluation of the properties of IEEE Std. P1149.4 test bus are presented.
