Boundary Scan - should be the most elaborate test process

Boundary scan is an electrical test method used to detect structural errors in a circuit. The scan test essentially means "testing on the periphery (boundary) of the circuit". To achieve this test, GOEPEL Electronics has developed the principle of interaction between various hardware components - the interaction between the following components:
·Controller,
·I/O modules,
· TAP transceiver and
· UUT.
