Abstract
New devices with security-critical functions like in money-or credit cards frequently have protective top metal layers in order to avoid unauthorized internal chip-access for testing or modifying the device. However, design/ process debug and FA need such access to accelerate learning for production ramp-up and design debugging. The paper shows a design approach how to allow authorized access for internal probing in such case.
