XJTAG was the first boundary scan solution to offer a common platform for use by design and development engineers, test engineers, contract manufacturers and field test engineers, providing testing of not only JTAG-enabled devices but non-JTAG devices as well.

JTAG is a technology that has existed for over a decade. However, its potential as a testing and programming tool is only just beginning to be fully realized. Advances in silicon design such as increasing device density and, more recently, BGA packaging has reduced the efficiency of traditional testing methods. In order to overcome these problems, some of the world's leading silicon manufacturers combined to form the Joint Test Action Group. The findings and recommendations of this group were used as the basis for the Institute of Electrical and Electronic Engineers standard.

However the technology has far more to offer. Non-JTAG-compliant sections of a circuit can be tested by using the interconnecting nets between the devices in the JTAG chain and other devices in the circuit.

Simple to install and use due to the USB plug-and-play ability. This allows you to easily move your licenses around on and off site to give you maximum flexibility.

Only a simple cable assembly is required to connect to your target board, no extra adapters are needed. The way connector on the XJLink2 is configurable from your test system. XJLink2 can work with a laptop PC with a USB port and can supply power to low-power target systems, so testing can be done even without a source of mains power. This is especially useful if testing has to be done in the field or in a very busy lab.

XJLink2 have variable signal termination, so they can handle boards both with and without signal termination.

Two different voltages can be configured, from 1. High speed USB 2. Spare pins on the JTAG connector can be used in place of the button or to indicate the test status. Voltage input: Min 0, Max 5V. Selectable measurement period of 1ms, 10ms, ms, 1s, 10s.JTAG was designed to remove the need for physical access, so it is now vitally important to get the JTAG chain right at the design stage.

Tools that utilize the JTAG capability do not come into play until after the first hardware becomes available, and they are often considered for manufacturing only.

Being able to validate the design early avoids board re-spins and costly delays to a project. Companies need to determine early in the design phase how to maximize test coverage using the minimum number of test points, so it is essential to know what JTAG access is available at the schematic stage of the design process. This allows test engineers to significantly optimize testing before their PCBs are produced.

Designing the panel is as important as the layout of the PCB itself. When designing a PCB, often the panelization is left up to the manufacturer. They are trying to optimize material usage and get as many boards on a panel and still conform to high yields and quality.

In cases where larger corporations design the panel design in-house, their focus is to have better control over the entire assembly process. A free plug-in for Design Gateway Play Related stories.

However, this presupposes that signals are mechanically reachable either at contact points or special test points. Miniaturization reduces the available space and makes it harder to place the required number of test points.

Boundary Scan is another test method that can be used as a supplement to the previous test methods. RAM, Flash, etc. The scope of delivery includes a case with the complete equipment, consisting of hardware and software, in order to carry out Boundary Scan Tests successfully. Likewise, your mounter who performs the test in production will also connect the boards.

The supplied software helps to create a complete test report.

JTAG implements standards for on-chip instrumentation in electronic design automation EDA as a complementary tool to digital simulation. The interface connects to an on-chip Test Access Port TAP that implements a stateful protocol to access a set of test registers that present chip logic levels and device capabilities of various parts. The Joint Test Action Group formed in to develop a method of verifying designs and testing printed circuit boards after manufacture.

The JTAG standards have been extended by many semiconductor chip manufacturers with specialized variants to provide vendor-specific features. In the s, multi-layer circuit boards and integrated circuits ICs using ball grid array and similar mounting technologies were becoming standard, and connections were being made between ICs that were not available to probes.

The majority of manufacturing and field faults in circuit boards were due to poor solder joints on the boards, imperfections among board connections, or the bonds and bond wires from IC pads to pin lead frames.

In the same year, Intel released their first processor with JTAG the which led to quicker industry adoption by all manufacturers. Ina supplement that contains a description of the boundary scan description language BSDL was added. Although JTAG's early applications targeted board level testing, here the JTAG standard was designed to assist with device, board, and system testing, diagnosisand fault isolation. Today JTAG is used as the primary means of accessing sub-blocks of integrated circuitsmaking it an essential mechanism for debugging embedded systems which might not have any other debug-capable communications channel.

Those modules let software developers debug the software of an embedded system directly at the machine instruction level when needed, or more typically in terms of high level language source code. System software debug support is for many software developers the main reason to be interested in JTAG. Frequently individual silicon vendors however only implement parts of these extensions. There are many other such silicon vendor-specific extensions that may not be documented except under NDA.

Processors can normally be halted, single stepped, or let run freely. Data breakpoints are often available, as is bulk data download to RAM. Most designs have "halt mode debugging", but some allow debuggers to access registers and data buses without needing to halt the core being debugged. Some toolchains can use ARM Embedded Trace Macrocell ETM modules, or equivalent implementations in other architectures to trigger debugger or tracing activity on complex hardware events, like a logic analyzer programmed to ignore the first seven accesses to a register from one particular subroutine.

For example, custom JTAG instructions can be provided to allow reading registers built from arbitrary sets of signals inside the FPGA, providing visibility for behaviors which are invisible to boundary scan operations. Similarly, writing such registers could provide controllability which is not otherwise available. JTAG allows device programmer hardware to transfer data into internal non-volatile device memory e.

Some device programmers serve a double purpose for programming as well as debugging the device. In addition, internal monitoring capabilities temperature, voltage and current may be accessible via the JTAG port. JTAG programmers are also used to write software and data into flash memory. Some modern debug architectures provide internal and external bus master access without needing to halt and take over a CPU.

In the worst case, it is usually possible to drive external bus signals using the boundary scan facility.
