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

Boundary Scan

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
