A functional simulator is used to describe a PLL (Phase-Locked Loop) type LSI in a hierarchical structure without using a circuit simulator that causes an unconvergent problem, and a functional simulation is performed. This hierarchical structure determines the specification division of the entire LSI. P
Among the LL system constituent elements, the element part for which the design parameter is to be determined is described by the circuit model according to Kirchhoff's rule, and the other element parts are described by the functional model according to experience, and the PLL system is constituted by the circuit model / functional model hierarchical structure A method of describing the whole was developed. This is named a hierarchical modeling technique. A hierarchical modeling technique was applied to a VTR color IC to prove its effectiveness.

した。The machine / circuit mixed system consists of different technologies,
It is necessary to design in a fused state. That is, if the actual parts of the mechanical system and the circuit system are simply connected separately, the design efficiency is deteriorated. Therefore, it is efficient to reproduce the mechanical system and the circuit system at the same time in the computer and fuse them together for designing. The function / circuit mixed simulator is used to describe the mechanical system and the circuit system in different structures to facilitate connection within the computer. Through this connection, the interaction between the mechanical system and the circuit system becomes clear, and the optimum design of the mechanical system and the circuit system is facilitated. In the computer, we have developed a method to describe the mechanical system of semiconductor technology and heterogeneous technology with a functional model, describe the circuit system of semiconductor technology and the same type of technology with a circuit model, and connect the functional model and the heterogeneous structure of the circuit model.
This is called the model connection technique. We applied the model connection method to a three-phase motor drive control system and proved the effectiveness of this technique.

た。It is wasteful to redesign a circuit that has been designed in the past from the beginning. An artificial intelligence language (Prolog) is used to describe an analog circuit with a hidden structure, that is, a circuit model is hidden with a functional model to facilitate reuse (automatic design) on a computer. Once hidden, it is registered as a library in the computer and continues to be reused thereafter. In the computer, the input part to the functional simulator is described by the functional model, the input part to the circuit simulator is described by the circuit model (netlist), and the concealment structure is described between the functional model and the circuit model. developed. This is named a detailed (circuit) modeling technique. The circuit modeling technique was applied to the DA converter to prove its effectiveness.
