Design support apparatus, design support program and design support method for supporting design of semiconductor integrated circuit

Abstract

A design support apparatus is provided, including control portion executes layout program to implement a position judging section which performs position judgment to check, for every net, the net being formed by a first cell to be called 'driver' and one or a plurality of cells driven via an output terminal of the first cell to be called 'receiver(s)', whether or not said driver exists outside a predetermined region for enclosing said receiver(s), and a layout section which determines a base point from an inside of said predetermined region, with respect to said net where it is judged that said driver exists outside said predetermined region, and arranges said diagonal wiring for wiring which connects said output terminal of said driver with said base point when said base point can be connected with an input terminal of said receiver by means of vertical and/or horizontal wiring.
