Abstract: The invention relates to a method of creating a requirement description for an embedded system, including but not only a motor vehicle electronic control unit, in which a vocabulary of natural-language, selectable text segments is stored in a data processing system, said text segments being combinable with one another to form at least one natural-language sentence, possibly but not necessarily in the English language, to form a machine-readable requirement description, and that each text segment is linked to a set of further text segments that can be combined with it, whereby for a text segment that is selected, the data processing system automatically represents the further combinable text segments in selectable form on a display unit. The invention further relates to a computer program product stored on a data medium that, when executed on a data processing system executes a method according to one of the previous claims.
