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.The class definitions may be one of the members and may be the address of the instruction in a memory of the processor being modelled, a record of any loops caused by the instruction, the opcode of the instruction describing the effect of the instruction when executed, a pointer to a description of the effect of the instruction when executed or an array of operands including input and output operant values for the instructions.
