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 in dependence 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 operand values for the instructions.

Abstract translation: 计算机被操作以通过将定义由系统处理的指令的类定义加载到计算机中来定义系统模型的电子数据，该定义包括系统对指令进行的一组功能方法，以及一组 代表指示的成员的地点。 然后在调用每个指令的类定义的计算机上执行模型执行程序，根据功能方法调用其中一个功能方法并加载具有状态信息的条目的位置以创建功能组件。 功能组件被加载到存储器中，并且功能组件的状态信息根据模型执行程序随后调用的功能方法进行修改。 类定义可以是成员之一，并且可以是被建模的处理器的存储器中的指令的地址，由指令引起的任何循环的记录，描述执行时指令的影响的指令的操作码， 指向执行时指令效果的指针或包含指令的输入和输出操作数值的操作数组。
