Boundary Scan Market Leader, JTAG Technologies invites you to join us at Embedded World in Nuremberg to discuss two hot board test topics :
Design for Testability (DfT)
The DfT challenge is the ‘Cinderella’ of the design process. Overcoming this challenge is not as exciting as designing and proving a new solution. Yet, DfT/testability should not be overlooked. A design that addresses testability without requiring add-ons that compromise the original scheme is every bit as fulfilling as seeing the first prototype roll off the production line. After all, without adequate testability, that new assembly’s debut will be delayed by revisions
