XJTAG Logic Library
From version 2.4 XJDeveloper and XJRunner support logic devices. A library of definitions for common logic devices is shipped with XJDeveloper. This post details this feature. […]
Categorising Devices as Logic in XJDeveloper
This post outlines how to categorise a device as a logic device in XJDeveloper and explains some of the useful features. […]
Design for Test Analysis in XJDeveloper 2.4 – Part 2
This post introduces the new DFT reports which are generated from the DFT analysis data. This is a feature introduced in XJTAG version 2.4. […]
Clearing Altera Cyclone III Devices
In the XJTAG application note “Working with configured Xilinx and Altera devices” the point is made that the way to get the best test coverage is to test with blank devices. Blanking a device has its own challenges – […]
Design for Test Analysis in XJDeveloper 2.4 – Part 1
The DFT Analysis screen in XJTAG version 2.4 has been completely redesigned to allow you to assess the test coverage of your circuit design more easily and in a more efficient way. This post highlights the most important new features. […]
Categorising devices in XJDeveloper – 10 rules of thumb
We asked one of the guys in-house who works with XJDeveloper most of the time to give some tips from his experience of setting up projects, and here is what he came up with: […]
Using CONNECT vs PULL in PDD files
Why use CONNECT not PULL for low-value pull resistors? When a resistor is specified as a pull resistor the XJTAG system will expect two things: […]
Logic in XJTAG – capabilities and limitations
We see a lot of logic components used on boards that come through our office. Most often we see buffers, bus transceivers and devices of that nature, but also plenty of the usual discrete logic chips – simple gates, decoders, encoders etc. […]
Using XJEase functions in XJRunner tests
A frequent question from customers is, “Why is my new XJEase test function not listed when I create an XJRunner test?” XJEase Functions For a function to be eligible to be made available to XJRunner it must be in the main project (.xje) file or a device file, or in a code file specified either [...]
Categories for selectors in XJDeveloper – part 2
Part 1 of this series explained how to add or edit the categories for the selectors in XJDeveloper. This entry will focus on using BOM (Bill of Materials) information in the selectors, using the demonstration board that comes with the XJTAG development system as an example. […]
