What is the meaning of the word “interconnect”? As the word is applied in the field of electronics, interconnect, as defined at Techopedia.com, defines the word as follows. “An interconnect (generally speaking) is a physical or logical connection between two electronic devices or networks.” Printed circuit boards (PCB) consisting of hundreds, sometimes, thousands, of interconnected integrated circuits (IC) and other active and passive devices are essential in today’s electronic world.
ASSET recently released an enhanced product for testing i.MX6-based board designs using JTAG. I fired up this new tool on the Boundary Devices SABRE Lite board, with some fun and interesting results.
We announced today the extended integration of ScanWorks’ boundary-scan test capabilities with the Teradyne’s PXI Express-based High Speed Subsystem (HSSub). Come see a demo at Booth #101 at the AUTOTESTCON conference!
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.
