Summary: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.
