The May 2018 issue of U.S. Tech features our article, “Triangulating BGA Faults with Boundary Scan“. View the article to learn how JTAG can be used to detect and diagnose manufacturing defects related to BGA devices.

Microsoft has declared that support for the Windows XP operating system has ended as of April 8, 2014; no further security updates and technical support will be provided. As a result, many organizations are upgrading their infrastructure with new systems running Windows Vista, Windows 7, Windows 8/8.1, and Windows 10 operating systems. End of Support for Windows XP Since Corelis ...

Shorting jumper shunts are frequently used to configure a unit under test (UUT) a particular way for boundary-scan testing–perhaps a compliance enable signal must be met or FPGA configuration needs to be inhibited. Because these shunts are meant to configure the system for test mode and could cause functional failures, it is important to ensure that test-only shunts are removed ...

Tip: Send a test log to your e-mail account using Blat Introduction Being notified when a test plan completes can be very useful for those times when you’ll be a way from the test station but need to know when the test has finished. Luckily it’s very easy to send a test log by e-mail using ScanExpress tools and the ...

IntroductionModern computer networks often employ technologies such as firewalls and Network Address Translation (NAT) to keep internal networks safe and secure. However, this extra layer of complexity can make connecting to simple network equipmen…

IntroductionScanExpress JTAG/Boundary-scan test execution tools with ISP capabilities (specifically ScanExpress Programmer & ScanExpress Runner) include capability to take in user data files and write them to Flash or other non-volatile memor…

You may have noticed in Corelis' Design for Test Guidelines a note on PLL clock buffers, and why they should be avoided when dealing with boundary-scan tests. PLLs contained in clock distribution ICs generally will not function correctly with a c…

IntroductionMany FPGAs in their preconfigured state include relatively strong internal pull-up/pull-downs, often in the 4.7k-ohm range or lower. If a weak pull-up/pull-down resistor is attached to such a pin, there is risk that the pull-up/pull-d…
