XJTAG 3.12 expanded the capability of the Signal Integrity Analysis in XJTAG tools, adding the ability to suggest certain causes of error. This post continues from the previous post on this subject, and describes further errors that XJTAG tries to identify. […]
(This updates an older article due to the addition of the Excluded category in XJTAG 3.12) One of the questions we are commonly asked by new users, and also by users who have not used XJTAG for a while and are coming back to it, is about the differences between device categorisations in XJDeveloper. […]
Historically we have provided three mechanisms for defining some form of constant or default values for a pin/net in XJDeveloper. These are BSDL compliance pins, bus disable values and constant pins, which allow you to define pins which XJTAG should keep in a constant state during automated testing, such as with Connection Test. However these approaches are profile- and subchain-agnostic. […]
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: […]
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. […]
The blog article ‘Debugging Connection Test – part 1 (Updated)’ discusses how to use ‘Debug Connection Test’ to identify a missing disable value. However, if a disable value is set to the wrong value, i.e. low rather than high, then it could prevent the Debug Connection Test from running at all. In this case, XJDeveloper’s Analyser screen can be used to help locate the issue. […]
With XJDeveloper 3.7 the user now has more control over how unfitted devices are suggested. The Unfitted Rules Dialog allows for the specific suggestion methods to be enabled or disabled, allowing for more accurate unfitted device suggestions. […]
Previously, when importing BOM information users were limited to making assignments from a selection of pre-defined BOM fields. With XJDeveloper 3.7 users can now define custom BOM fields. […]
The Bill of Materials, or BOM provides valuable information about the components in a netlist. This information is often key for project setups and, when available, is used by XJDeveloper to make project setup suggestions. This information is often taken from a separate BOM file or straight from a board’s netlist. With XJDeveloper 3.7 the volume of BOM data extracted for many of the netlist formats has increased. […]
It has come to our attention that the April 2018 feature update to Windows 10 causes XJTAG software to crash. This entry details the problem and what to do about it. […]
