The arrangement according to claim 6, wherein the data processing unit comprises a power calculation unit to produce actual power information, the status reports are transmitted to the data processing unit via the interface, and the power calculation unit calculates the actual power information using power information, which is available to the data processing unit, is stored in the data processing unit, and relates to the power budget for the emulated data processing system.

8. The arrangement according to claim 4, wherein the emulated data processing system comprises at least two modules each comprising a power calculation unit and a data store with stored power information relating to the power budget for the emulated data processing system.

9. The arrangement according to claim 8, wherein the power calculation units use the stored information relating to the power budget of the emulated data processing system to generate actual power information, which is transmitted first to a power information collection unit and then via the interface to the data processing unit.

10. The arrangement according to claim 4, wherein the user-programmable logic circuit comprises a measuring unit and the system to be emulated has at least two modules, wherein actual power values for a module can be converted into actual power information in the measuring unit and transmitted via the interface to the data processing unit.
