  • Patent number: 5371683
    Abstract: Disclosed is an LSI design support system for making a functional design of LSI using a graphic input method. This system comprises a state transition diagram preparation portion for preparing a state transition diagram, state transition table preparation portion for preparing a state transition table, and a state-operation circuit diagram preparation portion for preparing a state-operation circuit diagram. Data from these preparation portions are examined therebetween and the results are displayed at the same time on a picture plane so that a designer can efficiently make a design on circuit operation including its state transition. Also disclosed is another LSI design support system.
