A method for storing key data in an electronic component formed as an integrated programmable circuit, such as a field programmable gate array, which includes a base structure consisting of base elements, wherein configuration data is loaded, for each current program, onto the base elements and stored in a volatile matter, the key data is divided into key sub-data blocks, and a base element position is selected for each key sub-data block, where upon generating the configuration data for each current program or circuit function of the electronic component, selected base element positions of the key sub-data blocks are considered, while loading the configuration data, key sub-data blocks are stored in the base elements defined by selected base element positions, and after successfully programming the electronic component, the key sub-data blocks of base elements specified by selected base element positions are ascertained and assembled to form the key data.

A method for managing licenses for soft IP on a partially reconfigurable hardware system, in particular an FPGA, wherein a license manager is provided in the non-configurable part of the hardware system, or is accessible only for the non-configurable part of the hardware system, where the license manager has exclusive access to a non-volatile memory in which license data having a time restriction of the useful life of at least one soft IP is stored, where before activating a particular soft IP, the license manager checks whether the useful life has expired, where the license manager only releases use of the soft IP if the useful life has not yet expired, where the license data is changed using a key, which is stored in a non-volatile memory for license data, and where a new key is stored and the preceding key is deleted when the license data is changed.

A method for determining system reliability of a logic circuit, wherein a functional component model for design/simulation of a circuit model of the logic circuit is created, where functional components model are expanded by adding an associated power model, a temperature model, and a reliability, where the logic circuit is constructed with expanded model components and, based on simulation of the logic circuit aided by the constructed circuit model, a functional, a power-dependent, and a temperature-dependent behavior and a temperature-dependent failure rate are derived for each component in a component specific manner for a specified application case, and where in addition to the functional behavior, a power and temperature behavior and a total failure rate can be determined simply and dynamically, based on the derived data and dependent on temperature and simulation time for the logic circuit for the specified application case.
