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: […]
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. […]
Integrating XJTAG with other Test Systems – DFT
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. […]
Categories for selectors in XJDeveloper – part 1
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.
Archiving XJDeveloper Projects
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 [...]
Highlights of the 2.3 Release
This post outlines what is new in the 2.3 release. Some aspects will be explored in more detail in future entries. […]
Netlist Formats
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. […]
Pack Files
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 [...]
Netlist Explorer
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 [...]
Functional Tests
This post highlights the “Functional Tests” screen in XJDeveloper. The “Functional Tests” screen is in the “Design For Test” section in XJDeveloper. It is used to indicate to XJTAG that part of a board has been tested in some way outside of XJTAG. Doing this will make the DFT test coverage figures more accurate, and [...]
