<P>PROBLEM TO BE SOLVED: To perform layout design that achieves an optimum wiring efficiency in an analog circuit. <P>SOLUTION: Components constituting a function block are grouped for each type. Arrangement of the components within the function block is determined on the basis of a connection relationship between the components. At this point, the number of divisions for components constituting a group can be taken into consideration. The arrangement order of the function blocks is determined so as to perform arrangement in descending order of area or width. Preferably, the arrangement order can be adjusted by user's specification. The arrangement position of each function block is determined on the basis of the arrangement order and connection information for the entire circuit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
