Abstract: A method of automated generation of a set of design data defining a system model from an architecture database which is configured to hold in an electronic storage medium architectural parameters wherein each architectural parameter is defined by a primary key field and a set of fields holding subsidiary data relating to the primary key, the method comprising, reading the primary key for each architectural parameter, generating in an electronic storage medium a structured definition entry of the architectural parameter in an electronically readable format, the structured definition entry being associated with an identification field defining the parameter, and loading the primary key into the identification field and the subsidiary data into the structured definition file, and wherein the structured definition entry takes the form of a programming definition of the architectural parameter in a modelling language.

Abstract: A computer is operated to generate electronic data defining a system model by loading into the computer a class definition defining instructions which are processed by the system, the definition including a set of functional methods to which the instruction is subjected by the system and a set of locations for members representing the instruction. A model execution program is then executed on the computer which calls the class definition for each instruction, invokes one of the functional methods and loads the locations of the entry with state information depending on the functional method to create a functional component. The functional component is loaded into memory and the state information of the functional component modified independence on a subsequently invoked functional method by the model execution program.
