Windows 7 Support

Microsoft is ending mainstream support for Windows 7 on January 14th, 2020. This means that after this date updates to fix security issues will not generally be available and so machines running Windows 7 will be more vulnerable to security risks and viruses. We understand that many users will choose to continue using Windows 7 after this date, with some organisations opting to purchase extended support. We will therefore ensure that XJTAG continues to work on Windows 7 for the time being. However, due to Windows 7 not being in mainstream support, our products will not receive the same level of testing as they do for Windows 10 and we would encourage our users to upgrade to Windows 10 when possible.

A new WRITEABLE function in XJEase

For many years, the XJEase language has had the READABLE and WRITEABLE built-in functions. Their purpose is to try to work out whether it’s possible to read or write a pin before trying to do so. […]

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. […]

Using IIC to enable power supplies on your board

With the introduction of External Hardware per Subchain in XJDeveloper v3.9 it is possible to write a test that powers up your board using your XJLink2 to directly control the IIC pins before the JTAG chain is operable. Following is an example of how to set up this test in your project: […]

External Hardware available per-Subchain (including testing without JTAG)

Version 3.9 of XJDeveloper introduces the ability to control which External Hardware machines operate in each Subchain, and integrates this control into the Dynamic Chains feature. This means that any test may now be configured to use just JTAG, just External Hardware, or a combination of both, to drive signals on the circuit under test. […]

Editing configuration variables in XJTAG 3.9

Configuration variables in XJTAG allow settings to be configured for a device.  For example the address of an IIC device may need to be defined. Configuration variables are associated with a test device file, and in previous versions of XJTAG were only available in device files from the XJEase library. From XJTAG 3.9 configuration variables can be defined and edited in XJDeveloper. […]
