Abstract

An improved LSI design automation system includes: an input unit, a circuit component storage unit, a circuit component selection unit, a design method decision unit, a design process unit, and a component entry unit. The input unit receives LSI function and performance information as a requirements specification and LSI component configuration information. The circuit component storage unit collectively stores a circuit data item, design method information items, and performance information items, as a circuit component. The circuit component selection unit selects a circuit component from the circuit component storage unit for implementation of a desired circuit. The design method decision unit selects an optimum design method information item from the design method information items held by each circuit component. The design process unit generates, modifies, and evaluates a circuit. The component entry unit enters a result of the modification made during the design and a newly generated circuit component into the circuit component storage unit.
