extension of the boundary-scan architecture and new idea of bist for more effective testing and self-testing of interconnections
The approach presented in this paper enables more effective testing of on-board and board-to-board interconnections and significantly simplifies the interconnection self-testing. Some extensions must be added to the Boundary Scan Architecture which however do not violate the JTAG/IEEE1149 .1 standard requirements. Benefits are the reduced complexity and cost of an on-board testing unit as well as better test performance.
