About Eiger Design

Eiger Design GmbH is committed to designing and producing innovative test equipment, focussing on a high level of technical specification, ease of use, and flexibility. Based in Switzerland on the outskirts of Interlaken, close to the famous Eiger Mountain, our engineers are constantly looking at ways they can help make the design of UUT functional testers faster, simpler and more efficient.



JTAG & Ethernet Controllable Universal Functional Tester

J-Testr has both Ethernet and native JTAG communication interfaces so users can work with JTAG boundary scan tools and more conventional functional test software or scripting languages like Python. Driver examples for common Test Executives, scripting languages and JTAG test platforms are provided to allow users to choose their own preferred test software environment and operating system. 

The J-Testr programming interface has been designed for flexibility, speed and simplicity. All internal functions are accessed via simple memory mapped 16-bit register sets, making any engineer with some micro-controller knowledge instantly at home. 

Advanced debugging tools such as the ‘free’ open-source J-Debugr graphical debugging tool and low cost breakout cards help test engineers develop test code with ease, speed and confidence.  

The J-Testr is designed with 'test in mind' and includes many advanced features to make testing both simple and safe. This includes the unique ‘J-Safe’ technology which provides high speed system shutdown in cases where the UUT may be at risk of damage.  

Multiple UUT mounting options, including ‘bed of Nails’, allows the most suitable mechanical solution to be selected dependent on test volumes and budget.
