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. As well as the preparation portions in the above system, this system comprises a transitional-condition analysis portion for analyzing transitional conditions of a state transition diagram obtained by the state transition diagram preparation portion or a state transition table obtained by the state transition table, an automatic-layout-wiring program execution portion for preparing a state transition diagram by data from the state transition table, and an automatic-table-preparation program execution portion for preparing a state transition table by data from the state transition diagram.
