چکیده

This paper describes an application of boundary scan IEEE Std. 1149.1 at system level. It provides the description of the design and the implementation options of a VME boundary scan controller board prototype and the corresponding software. The prototype was designed to use the Module Test and Maintenance (MTM) bus, existing in the VME 64x backplane, to apply the IEEE 1149.1 test vectors to a single board with a specific test infrastructure also described in this contribution. The software takes the boundary scan test/programming vectors generated by an automatic test pattern generator (ATPG) in serial vector format (SVF), and converts them into a format suitable to be used in the considered test infrastructure.

Embedded Boundary-scan Testing

Boundary-Scan testing is used more and more to overcome many of the testability issues facing today’s higher density designs. In the past, Boundary-Scan has been used successfully with ATE’s and external PC based test systems. Since Boundary-Scan tests are structural in nature, they can be reused with often minor modifications in the embedded arena. Further, these same tests can be used in the ...

Forensic imaging of embedded systems using JTAG (boundary-scan)

This paper describes how to use JTAG (JTAG: Joint Test Action Group, also called boundary-scan) for producing a forensic image (image: an one-on-one copy of data found on an exhibit) of an embedded system. A JTAG test access port is normally used for testing printed circuit boards or for debugging embedded software. The method described in this paper uses a JTAG test access port to access memor...

SCANPSC100F Embedded Boundary Scan Controller (IEEE 1149.1 Support)

The SCANPSC100F is designed to interface a generic parallel processor bus to a serial scan test bus. It is useful in improving scan throughput when applying serial vectors to system test circuitry and reduces the software overhead that is associated with applying serial patterns with a parallel processor. The SCANPSC100F operates by serializing data from the parallel bus for shifting through th...
