When a global provider of air traffic, navigation, and landing system solutions began implementing its next-generation system, limitations of an existing test and debug methodology directly impacted ...

Since its adoption as an IEEE standard in 1990, boundary scan has offered engineers an important tool for testing complex circuit boards. Harry Bleeker of JTAG Technologies, who initiated the work on ...

Boundary scan offers clear advantages over technologies that require physical contact with a unit under test. It is also useful for ferreting out faults among the expensive, advanced semiconductor ...

Boundary scan, based on IEEE Standard 1149.1 and related specifications, has become widely used to solve difficult test problems on complex PCBs. The difficulties arise due to lack of access needed by ...

XJTAG selected by ARM due to power, performance, versatility, and cost-effectiveness With XJTAG, ARM is meeting its target for 90 percent test coverage for digital connects and ten-minutes-per-board ...

A method for testing chips on the printed circuit board by building the chip with additional input and output pins that are used only for test purposes. Full scan methods test all the registers on the ...
