System-Level JTAG with ScanWorks Dispatcher
Building upon the board-level and system-level guidelines presented in the Design for Test eBook series, in this fourth eBook we examine a software application developed by ASSET InterTech named ScanWorks Dispatcher.
System-level JTAG, or SJTAG, is well-suited for functional tests, device programming, and in-situ diagnostics. It expands the application potential of JTAG significantly beyond the traditional board-level scope of structural tests. When boards are assembled into a system, faults can arise, even with boards that have been previously tested with JTAG. With proper application, JTAG is perfectly suited to detect faults between boards that have been assembled in a system.
ScanWorks Dispatcher is a flexible, high-speed, parallel, boundary-scan test and in-system programming application system for high test throughput. ScanWorks Dispatcher, along with implementing various JTAG architecture designs, multi-drop devices, multi-Test Access Port (TAP) hardware, or embedded software applications, can significantly increase board test coverage and manufacturing throughput.
