Abstract
In one approach for protecting a design, a plurality of implementations of the design are generated. Each implementation includes an identification function. One of the implementations is selected as a current implementation, and the current implementation is installed on one or more electronic systems. For each electronic system, a method determines whether or not the current implementation is an authorized version on the electronic system from an output value of the identification function. If in the current implementation is not an authorized version on the electronic system, a signal is output indicating that the current implementation is not an authorized version on the electronic system. Periodically, another one of the implementations is selected as a new current implementation, and the new current installation is used for installations on one or more electronic systems.
