The Hardware Concept
An appropriate and high-performance hardware platform is necessary to make full use of the possibilities provided by JTAG/Boundary Scan technology and the numerous new IEEE 1149.x standards.
Dedicated to meeting this challenge since 1991, GOEPEL electronic has the broadest and most powerful range of products currently available in the world – in the form of the PicoTAP and SCANBOOSTER controller families, as well as the SCANFLEX system platform.
At the same time, our development strategy focuses especially on securing investments already made by providing updates and upgrades.
