JTAG/Boundary Scan is probably the most ingenious test process,
which like ICT, tests within the circuit and detects structural fault locations by setting thousands of test points, even under BGAs, - with only four test bus lines.
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 controller, I/O module, TAP transceiver and UUT.
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.
The JTAG/Boundary Scan solution: SCANFLEX
JTAG/Boundary Scan system architecture SCANFLEX consists of three components: Controller, TAP Transceiver and I/O Module:
