Welcome to the XJTAG blog
We believe that sharing our knowledge will help you get the most out of your XJTAG system. This is where our development and support team share their insights and experience. You’ll find posts highlighting particular features of the different software packages that make up the XJTAG development system or aspects of the XJEase language.
Above all this blog is for YOU. We’d love to hear your feedback and suggestions for topics.

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. […]
Migrating from XJRunnerIntegration.dll to XJIntegration.dll
Much of the content in the XJRunner .NET Integration is also relevant to the XJAnalyser .NET Integration, which is new for XJTAG 3.9. Therefore we have taken the decision to combine the two into a single new assembly, XJIntegration, which means that resources can be shared between the two integrations, and allows them both to be used in the same application if required. […]
XJAnalyser .NET Integration
In XJTAG 3.9 the previous .NET-based integration has been replaced with a new XJIntegration API. The new API still uses .NET 4.7.1 and contains all the XJRunner Integration functionality of previous releases – but also introduces XJAnalyser Integration, a new .NET API for XJAnalyser. […]
