User XJEase Libraries – part 2

The second part in this 2 part series about the new user libraries feature in XJDeveloper 3.11 will explain how user libraries are useful in XJDeveloper. When devices are categorised using library files (as opposed to using files saved on disk) you can re-use these library files in other XJDeveloper projects with ease and all projects can be automatically updated when a file is modified. […]

Stuck-at testing on 1149.6 pins

One of the standard types of testing that is done in XJTAG’s Connection Test is to detect stuck-high and stuck-low faults (shorts to power/ground). Using the IEEE 1149.1 JTAG standard this can be done providing the net has full IN/OUT functionality – that is to say it can both drive output and read input at the same time.  The test is implemented by driving the net high or low and then checking that the value read from the net changes to reflect the value driven. […]

PCOLA/SOQ Test Coverage in XJTAG. Part 1.

PCOLA/SOQ is a unified way to assess the test coverage offered by testing systems. Rather than directly considering what the test system can detect, it starts by considering everything that could be at fault in the device under test, and then scores how well the test system could identify such faults. […]
