Are you ready to overcome the limitations of JTAG/Boundary Scan?

Beyond boundaries

To test electronic assemblies, the JTAG/Boundary Scan test procedure was revolutionary at the time and represented a technological leap. But it was not the possibilities of testing digital components, which were considered an excellent, cost-effective supplement to other test procedures, that made the so-called JTAG test a viable instrument for the future. The true value lies in the limitless possibilities that the standard IEEE 1149 opened up.

The latest JTAG technology - the Embedded JTAG Solutions

The possibilities are so diverse that we call our testing and programming solutions ‘Embedded JTAG Solutions’. They stand on the three pillars of different technology and application areas that you may already know: Embedded Board Test, Embedded Functional Test and Embedded Programming. These three pillars describe concrete application scenarios that may confront you every day in your electronics development or production.

The performance levels: Standard, Professional and Expert

These three pillars however, are by no means the entire range of services. This is because we subdivide all three pillars into another three horizontal levels - the performance levels: Standard, Professional and Expert. The lowest ‘Standard’ level describes classic test and programming procedures based on the IEEE 1149.1 Boundary Scan Standard. The Professional and Expert levels are far above this in terms of performance. They use integrated chip resources and enable the highest testing and programming speeds for demanding and complex electronic assemblies.

The resulting matrix provides a complete overview of the Embedded JTAG Solutions and their applications. Behind it are numerous hardware products such as SCANFLEX, SCANBOOSTER or CION as well as the software platform SYSTEM CASCON.

Embedded Board Test

The Embedded Board Test is used to check functional board connections. For example, short circuits, unsoldered pins or missing pull resistors are detected.

Embedded Programming

On-chip or external flash devices are programmed using boundary-scan and hardware resources. In particular, increasing file sizes and the resulting growing demands on programming speed are key elements in today's assembly production.

The programming speed depends on the amount of data to be transferred and depends on many factors. Without knowledge of the application, precise statements are therefore generally not possible. Information about the speed is always subjective and depends on the application as well as the benefit.
