Abstract: The invention relates to a process for the parameterization of a software-implemented working model of a simulation environment, which comprises a multitude of simulation model components and is loaded onto simulation hardware, particularly in order to simulate a test environment of at least one motor vehicle control system interfaced with the simulation hardware or the simulation of a motor vehicle control system running on the simulation hardware, whereby the working model is analyzed in relation to the simulation model components contained therein and for each detected simulation model component there is generated and displayed a user interface by the automatic selection out of a mask databank of at least one input/output mask allocated to the simulation model component and by the automatic selection out of a parameter-mask allocation databank of the parameters allocated to an input/output mask.
