XJTAG Blog

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: Read the rest of this entry »

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. Read the rest of this entry »

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 in the main project (in the Circuit Code Files Screen) or from within a test device file (in the Test Device Files Screen).

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.

This series of posts will cover how you can integrate XJTAG into your overall test system.

This post is a quick reminder that you can use XJTAG as the focal point for your DFT analysis across all your test systems.

This post discusses the selectors in XJDeveloper and how you can customise them. Selectors are used whenever you have to select either a Net or a Device. Entries in a selector are grouped into categories that can be customised.

There are two ways to export projects from XJDeveloper either exporting to an XJPack or a zip file. Both options  are found on the File -> Export menu in XJDeveloper.

XJPack files are used by XJRunner in production. When you have finished creating your project in XJDeveloper, “pack” it and then this file can be used in production.

Zipping a project will create a single zip file that contains all the files used by the project. This can be useful if you are sending a project to another department, or for creating regular backups of your project.

In versions of XJTAG prior to 2.0, the system supported just four netlist formats: RINF, EDIF 2, PADS PCB and Protel. The parsers for these netlists were written carefully against specifications for the formats where possible, and so should reliably parse all valid netlists in those formats.

This post covers XJPack files – the XJTAG mechanism for deploying your tests to production.

XJDeveloper is used to write your tests and can run your tests whilst you are creating them. In a future version it will also integrate the debugging functionality of the command line tool XJDebug to allow you to debug your tests from within XJDeveloper.

This post details the Netlist Explorer in XJDeveloper, a very useful tool in XJDeveloper for finding out how things are connected in the netlist. It also shows relevant properties for each item.

Launching the explorer

Currently the Netlist Explorer is a modal dialog which means you have to close it before you can use the rest of XJDeveloper. We hope to remove this restriction in a future release. You can launch the Netlist Explorer from most screens in Developer. All relevant toolbars have an “Explore” button, and right-clicking on items in controls will display a drop-down menu with an “Explore” button as well.
