YI Weihua, GAO Feng, CHEN Zhiman, et al. Boundary-scan Test for High-density Digital Board[J]. Electric Drive for Locomotives, 2015,(1):83-86. DOI: 10.13890/j.issn.1000-128x.2015.01.024.
With boundary-scan method, a high-density digital board was tested, which increased the test coverage and faults coverage, and could diagnose and locate faults automatically. It conquered the bottleneck problems of CPU system and its I/O circuits test.
