Abstract

Driven by the industrial need for low-cost test methodologies, the academic community and the industry alike have put forth a number of efficient test data compression (TDC) methods. In addition, the need for core-based System-on-a-Chip (SoC) test led to considerable research in test access mechanism (TAM) design. While most previous work has considered TAM design and TDC independently, this work analyzes the interrelations between the two, outlining that a minimum test time solution obtained using TAM design will not necessarily correspond to a minimum test time solution when compression is applied. This is due to the dependency of some TDC methods on test bus width and care bit density, both of which are related to test time, and hence to TAM design. Therefore, this paper illustrates the importance of considering the characteristics of the compression method when performing TAM design, and it also shows how an existing TAM design method can be enhanced toward a compression-driven solution.
