Now that At-Scale Debug (ASD) is becoming a de facto standard on Intel designs for the remote execution of CScripts, what other applications can take advantage of this technology?
ASSET’s Michael Johnson presented an update on Non-intrusive Board Test (NBT) at the 13th Annual Board Test Workshop (BTW) in Fort Collins, CO this past week. The overall question posed at the Workshop was, “Is Board Test Losing Relevance”?
The MSP430 is a mixed-signal microcontroller family from Texas Instruments. Built around a 16-bit CPU, the MSP430 is designed for low cost, low power consumption embedded applications. But, does it support boundary scan for board test purposes?
In recent years, the increasing size of flash memory has driven device programming to offline methods. However, new techniques are significantly reducing in-system programming times, making it much more feasible and convenient to program flash memory after it’s already been soldered to the board.
Recently launched DDR4 devices have what memory device vendors may refer to as a “boundary scan” test mode. Even though there’s not really a boundary-scan function involved on the DDR4 side, this mode actually has been, as claimed by JEDEC, “designed to work seamlessly with any boundary-scan devices.” Here’s a brief introduction to what it does and how to test it with a boundary-scan (JTAG) tool.
As described in earlier blogs, the new Intel Innovation Engine (IE) makes an ideal host for validation, debug, trace and test applications on Intel platforms. This article details the implementation of a JTAG execution engine on the IE for the purposes of printed circuit board structural and functional testing.
Last week, I wrote about Intel’s public announcement of the Innovation Engine (IE), an Intel architecture processor and I/O sub-system embedded into their upcoming generations of server platforms. This article describes the use of the IE for JTAG boundary-scan testing of memories.
