Title:
METHOD FOR DESIGNING LAYOUT OF INTEGRATED CIRCUIT
Document Type and Number:
Japanese Patent JP2001291775
Kind Code:
A
Abstract:

To provide a method for designing the layout of an integrated circuit capable of effectively reducing a power source noise, and reducing the increase of a semiconductor chip area.

A power source noise generated in a circuit block is calculated by referring to a load capacity connected to the output terminal of the circuit block and a rising and falling time, and outputted as power source noise information in a step S5. A by-pass capacity for setting a prescribed power source noise level or less is selected from a noise by-pass capacity table 13 by referring to the power source noise information and the noise by-pass capacity table 13 in a step S6.
