If you do run into trouble we provide a Support Forumand precise Documentation. We on Facebook.Much more than a production line test tool, XJInvestigator is a repair focused, integrated test and debug environment for fault analysis, helping you efficiently recover your failing boards.

XJInvestigator is much more than a production line test tool, it allows you to quickly identify faults and get boards re-worked and re-tested. You can then visualise any fault on both the schematic and layout of the board using the integrated viewers. If the production line tests cannot be run on a board due to problems with the scan chain then the built-in JTAG Chain Debugger helps you quickly identify these faults so normal testing can continue.

To ensure consistency in the testing process the predefined test functions cannot be modified however XJInvestigator offers the extra flexibility and configuration options needed to help you to track down faults. When a problem has been identified with a board you can select individual tests, sets of tests or additional functions not included in production testing to run. The tests can also be run continuously to help diagnose particularly tricky or intermittent problems.

Simple ad-hoc tests can be implemented very quickly by controlling and monitoring signals on the board from your JTAG-enabled devices, even BGAs. On the Analyser screen, pin values can be set to toggle or to be driven high or low. The values of pins read from the board are shown in a simple colour-coded display. XJInvestigator can scan and store the values being driven onto the JTAG devices of a known good working reference board.

These values can then be compared with those captured from boards exhibiting unexpected behaviour to highlight inconsistencies. You can put pins into a watch window allowing you to easily establish the relationships between them, even when they are from different JTAG devices.

You can also build groups of pins into busses and then write values to the busses and monitor their values for more efficient testing. Full Connection test. View pin states graphically in real time or capture them in the Waveform Viewer. Trace signals to identify shorts, opens and other faults. Improve your diagnostic capabilities in production repair XJInvestigator is much more than a production line test tool, it allows you to quickly identify faults and get boards re-worked and re-tested.

The problem was cause by the software. JTAG standard only defines a few hardware pinouts. However there is no standard definition on the PC side, e. With provided flexible jumper wire you can move the pin configuration easily to suit different programmers. PW is the power output. If you connect the power header to a component requires more current, it will damage your USB port. If you want to use it in unbuffered mode, you do not need to connect the USB cable. Bin is the buffer input header.

We use 74HCT as the buffer chip. Bout is buffer output header.

The product comes with 6 x 50cm color coded flexible cable and 6 x 10cm color coded flexible cable. If you want to use the adapter in unbuffered mode, you only use the 6 x 50cm flexible cables.

In buffered mode, you will need pieces 10 cm flexible cable and pieces of 50 cm flexible cable again, they come with the package.

You can connect your cable modem and your pc via JTAG cable to do some interesting test, such as change MAC address, serial number, bootloader and firmware. Motorola has a 10 pin header and Webstar has a 8 pin header. Now connect your universal JTAG adapter to your PC's parallel port, turn on the modem, launch the blackcat software and have fun modding it!

If you do update with the latest xboxlive update homebrew will never run on that xbox again even if the update is done after the mod. We do not recommend run it in unbuffered mode.

You can use the viewer to quickly understand how a device is being used in a circuit, to help identify faults and debug tests. Simple links take you straight from your XJTAG system and highlight the relevant section of the schematic in the viewer, while the intelligent netlist search allows you to navigate directly to other elements of the circuit. For manufacturers to use the viewer in XJRunner, you have to explicitly export the schematic information from XJDeveloper.

Conversely, if your schematics need to be kept confidential, do not export them to XJRunner. Whether you are developing tests or debugging boards, searching for a device, net or pin on a schematic is a common task. The Schematic Viewer simplifies this process using its smart textual analysis as well as PDF bookmarks to take you to the most relevant section of the schematic.

The viewer is very helpful when setting up your XJTAG test system as you can use simple context menus to view the section of the schematic related to any device. These menus are available throughout the system and can be used at every stage of the setup, even when reviewing the test coverage that XJTAG reports in its Design For Test analysis.

Once you receive your first prototype hardware and start running tests, the Schematic Viewer saves you time and effort by allowing you to navigate directly to those nets identified as faulty. This can help you understand whether any problems are caused by real hardware faults or are simply configuration issues — such as unfitted components. If you need to check if a device has been correctly fitted to your board you can use the XJTAG Layout Viewer to pinpoint its physical location.

The viewer can be used with the output from any schematic capture tool that can produce standard PDF documents. Advanced Connection Test. High-Speed Flash Memory Programming. Layout Viewer. Schematic Viewer. Waveform Viewer. BSDL Editor.

Fanout considerations and chain cycle speed would enter into the decision as to how long a chain to implement. Refer to the DFT booklets for more information. There is no limit to the number of chains that the JTAG Technologies software can handle, and there is no loss in test coverage if you decide to have multiple chains.

In many cases, partitioning your board into more than one chain will give you greater design flexibility and may improve the performance of your boundary-scan operations.

Therefore, we strongly recommend that you consider using more than one chain on your board. For more detail, refer to our DFT booklets, one for board-level design and the other for system-level design.

If it is compliant, it should say so in the notes. Also check the BSDL for special compliance requirements. In some cases it may be necessary to hold specified pins at defined voltage levels for the part to perform boundary-scan operations. In many cases, only a fraction of the ICs on a board need to contain boundary-scan in order to test a significant number of nets.

Also, through the use of DIOS modules, you can greatly increase the test coverage. Very little.

Boundary-scan helps eliminate or reduce the number of test points required on a board and may result in a net saving of real estate and a simpler layout. The space required to add a small number of passive devices for TAP lead termination and the TAP header is often offset by the test point reduction. We offer training courses to match your needs.

Training for use of the production tools, such as PSA, the stand-alone run-time tool, requires half a day, including the use of the diagnostic software. More about training.

The graphical tooltip shows you instantly the details for any net or node. There is no standard for the TAP connector.This document provides you with interesting background information about the technology that underpins XJTAG. Advances in silicon design such as increasing device density and, more recently, BGA packaging have reduced the efficacy of traditional testing methods. This standard has retained its link to the group and is commonly known by the acronym JTAG.

The main advantage offered by utilising boundary scan technology is the ability to set and read the values on pins without direct physical access.

The process of boundary scan can be most easily understood with reference to the schematic diagram shown in figure 1. In normal operation these boundary scan cells are invisible. Not all boundary scan cells are the same — there are 10 types of cell in the There are two types of registers associated with boundary scan. Each compliant device has one instruction register and two or more data registers.

Instruction Register — the instruction register holds the current instruction. Its content is used by the TAP controller to decide what to do with signals that are received. Most commonly, the content of the instruction register will define to which of the data registers signals should be passed. Other data registers may be present, but they are not required as part of the JTAG standard. Figure 2, below, shows the state-transition diagram.

The two main paths allow for setting or retrieving information from either a data register or the instruction register of the device.

The data register operated on e. The IEEE These instructions are:.
