Abstract

A method for optimal arrangement of a random generator on an electronic component, which includes a programmable integrated circuit and a basic structure consisting of a plurality of basic blocks, wherein during an initialization phase, starting from a starting configuration for a respective current arrangement of the random generator, the following are performed with a predefined number of repetitions, i.e., a predefined test sequence is performed for the current arrangement of the random generator, a test result is forwarded to a reconfiguration module and the current arrangement on the electronic component is reconfigured via the reconfiguration module, where upon each repetition, the test result of the current arrangement of the random generator is compared with the test result of a previous arrangement, and the current arrangement is saved in the reconfiguration module, if the test result for the current arrangement has a better test result than the previous arrangement.
