摘要

PROBLEM TO BE SOLVED: To facilitate changes, such as hierarchical movement of a RAM and a change from non-sharing to sharing of a RAM or a change from sharing to non-sharing of a RAM in LSI design, and to reduce the design man-hours and design mistakes.;SOLUTION: A circuit block diagram creation device includes a RAM selection means (12) for determining the selection of a RAM for sharing from data of RAMs disposed in a circuit block; a RAM moving means (13) for moving the data of the RAM whose selection has been confirmed to another block; a RAM interface circuit creation means (14) for automatically creating a RAM interface circuit required according to the movement of the RAM data; and circuit description source code creation means (15) for automatically creating a circuit description source code (16) in which the operation of the circuit is described.;COPYRIGHT: (C)2011,JPO&INPIT
