What is Boundary Scan? What is a scan test?

JTAG/Boundary Scan - is probably the most ingenious test process

Boundary Scan
The principle of an scan test

Boundary Scan is an electrical test method, detecting structural errors in circuits. Scan test essentially means “testing at the periphery (boundaries) of a circuit”.

In order to implement this sort of testing, GOEPEL electronic has developed the principle of interaction of various hardware components – interplay between

All GOEPEL electronic hardware products are completely supported in the JTAG/Boundary Scan software platform SYSTEM CASCON. Thereby, the test programs are cross-compatible between the controllers.

The integrated JTAG/Boundary Scan software environment can be utilised throughout the entire product life cycle.
