A customer shared some empirical results from boundary-scan testing of the Intel QuickPath Interconnect (QPI) nets on their design. These nets cannot be covered using In-Circuit Test (ICT), and some short-circuit and open-circuit defects defy detection using conventional functional test. What did they find?

Boundary scan is known to be quite slow to program large flash devices. But, with a new approach using SPI Master IP within an FPGA, flash programming time can be decreased by a factor of 15 or more.

To quote Ransom Stephens in the DesignCon Community Blog, “BIST (Built-In System Test), is an acronym that would keep executives at test-and-measurement companies awake at night, if they knew what it meant.” What’s he talking about?
