The large integration scale of contemporary electronics, the extremely small dimensions of PCB boards and components, the use of surface mount parts in BGA or TSOP packing cause that the pins could not so easily be probed and hence tested by traditional ICT testers or by traditional measurement equipment. From other side for more and more complicated electronics it becomes more and more difficult to prepare easy to maintain production tests covering all possible damages. To automatize testing and test generation, to increase test coverage it’s also a challenge for engineers. So testing became a problem for developers in research departments, for test and quality engineers on production lines and for repair services. Each of them has different requirements and expectations. JTAG Technologies brings up a set of complementary tools for all these areas that can help a lot to precisely identify faults.
JTAG Technologies tools and solutions can be group as follows:
This flexible set of tools can be configured in different packages depending on concrete application. Experienced staff of an authorized distributor WG Electronics can be helpful in choosing the right options for one of following applications.
Today’s hardware engineers are faced with ever increasing pressure to deliver more complex products with precise specifications to a market fast. One of their greatest challenges is how to debug prototype boards for unforeseen manufacturing faults. This is an area where JTAG Technologies can help. By ensuring that a workable boundary-scan infrastructure is designed in from the start, the hardware engineers are building-in a permanent debug mechanism into their design - a mechanism that can be used by you, your colleagues and partners throughout your product's life-cycle.
Benefits:
- Reduce development costs, speed time to market
- A firmware independent way to prove your prototype hardware
- Early testability feedback during schematic stage
- Screen your prototype against manufacturing failures
- Save time in developing functional tests
- Control how your design will be tested during production
- More time developing, less time testing and debugging

Today most hardware engineers undertake some software or firmware development and some software engineers even undertake hardware development. What they both have in common is the need to program their code into the many programmable elements that now exist on today's digital and mixed signal designs. For a complex board that could include an array of parts such as Flash Memories (NOR and NAND), Serial PROMs (I2C, SPI etc..), CPLDs, FPGAs, microprocessors and DSPs with embedded flash. SOCs etc.. For many engineers the problems occur when trying to accommodate the array of ISP (In-System Programming) interfaces and hardware adapters needed to support these devices. By using the tools from JTAG Technologies you can obtain the following benefits.
Benefits:
- A single point of entry for all ISP requirements
- Uses standard JTAG controller compatible with hardware engineering and test
- Supported by intuitive, generic software interface with built-in sequencer
- Programs flashes (NOR and NAND) plus serial PROMs using indirect JTAG
- Programs embedded flash in Micros and DSPs
- Configures all types of CPLDs and FPGAs using SVF, JAM/STAPL, JEDEC and ISC (IEEE 1532) format
JTAG Technologies offer a comprehensive selection of best-in-class factory test and device programming solutions. Whether you are an OEM or a contract manufacturer, JTAG technologies has a run-time solution targeted to meet your needs. Choose a stand-alone boundary-scan system or one of our many integration alternatives for in-circuit, flying probe, in-line, or functional testing. JTAG Technologies are the preferred boundary-scan vendor for many of the world's leading production automation companies.
Benefits:
- Reduce costs and shorten your time to market. Boundary-scan shrinks test development times, decreases debug time for prototypes and expedites re-programming. Test fixtures are greatly simplified and may be eliminated altogether.
- Increase accuracy - start test engineering earlier in the product cycle, based on pre-layout design information and using time saving automated tools. Test programs are ready at the start of production, complete with high-resolution diagnostics for repairs.
- Improve beat rate - boundary-scan ensures PCBs are correctly assembled and programs flash memories and PLDs in-system at high throughput rates.
Diagnostics from JTAG Technologies' tools give you precise, easy-to-read results, rapidly highlighting short-circuits, open pins, open nets or even swapped or 'twisted' interconnections that might appear between two sub-systems. By adding JTAG Visualizer to your repair station, you can see the exact point of failure graphically on either your schematic diagram or layout for quicker and easier repair. A typical boundary-scan repair station consists of a runtime system based on ProVision platform with its built-in test executive (AEX) plus diagnostics software and JTAG Visualizer. Since diagnostics can be included with the production or returns test failure report there is no need to re-run tests during repair.
Lower your repair time cycle. Reprogram and reconfigure PLDs and flash memory on field returns easily without having to remove ICs from the boards. Uncover faults rapidly and pre-screen boards before functional verification. Use our run-time and diagnostic tools on your board returns for fast, precise analysis of faults, and to easily update firmware to the latest version. Unique AutoBuzz software learns and compares 'connectivity signature'.
Benefits:
- Rework - increase diagnostic capability
- Re-use tests and programming applications from original production sequences
- Compact JTAG tester hardware is easily transported to the point of test
- Retests and reprograms boards and systems
- Compatible with Visualizer viewing software
