Embedded JTAG Solutions Application Examples

Debugging, Testing and Programming

Xilinx Zynq-7000-SoCs (System-on-Chip)

The Xilinx Zynq-7000 All Programmable System-on-Chip (SoC) series offers a high level of programmability to the highly flexible design of SoC-based solutions.  


Main application areas of the Zynq devices are control, communication, safety technology, system management and system analysis.


The in-system technology ChipVORX configurates and controls test, debug and programming functions for the Zynq 7000 SoCs. The ChipVORX models contain all necessary structural and functional information for controlling the embedded hardware at the command level.

Application example: Helmut BEYERS

The electrical test with the JTAG/Boundary Scan

Helmut BEYERS GmbH is a medium-sized contract manufacturer, based in Mönchengladbach. The company works on behalf of OEM customers from the telecommunications , medical and building technology sectors. There are increasing enquiries from the fields of Intelligent electronics for Industry 4.0 and Smart Home applications. From Pilot Series and Prototypes to batch sizes of 50,000, the production scales flexibly and also implements demanding technological customer requirements.


  • in some cases customers require an error tolerance of <1%
  • difficult testability due to high use of BGA and missing test points
  • supplement to In-Circuit Test  necessary
  • compliance with Cycle rates

Our Solution

Production Tester JULIET

  • combination of test strategies for almost 100% test depth
  • quick adaptation of test subjects
  • test system in combination with automatic component group progamming to save time
  • fully automatic programming of all ICs directly integrated in the test process

Application Example Infineon

Testing and Programming Infineon Automotive Power ICs with VarioTAP

The latest generation of the Infineon AURIX MultiCore devices and the TLE987x family from the field of automotive and embedded power are particularly suitable for control applications such as:

  • fuel pumps
  • HVAC blower systems
  • sensor-based motor control
  • safety-critical applications


Space-saving BGA or VQFN-48 packages usually don’t allow direct contact with external instruments.



Our Solution

VarioTAP provides access to the built-in resources through its test structures. This allows generation of static and dynamic test patterns, which can also be combined with other test methods (e.g. Boundary Scan). As a result, structural tests are expanded, functional and diagnostic tests are possible in the first place.


Functional Circuit Tests for Energy-Efficient i.MX6 Multimedia Processors from NXP

Based on the ARM® Cortex ™ -A9 architecture with up to four cores, the i.MX6 processors from NXP have been specifically designed for entertainment, industrial and automotive applications. The focus of the functionality is a combination of the latest 3D / 2D HD graphics technology with efficient energy management.

JEDOS executes special test and programming procedures for the i.MX6 family:

  • test and calibration of DDR devices
  • test of high-speed interfaces (PCIe)
  • loading of flash devices via external media or communication interfaces
