SEMICONDUCTOR INTEGRATED CIRCUIT, METHOD FOR DESIGNING SEMICONDUCTOR INTEGRATED CIRCUIT AND SYSTEM FOR DESIGNING SEMICONDUCTOR INTEGRATED CIRCUIT

The semiconductor integrated circuit capable of reducing an interconnection width as compared with conventional one while suppressing electromigration effectively. An input unit 101 stores interconnection information in an interconnection information storage unit 104. An arithmetic operation unit 102 acquires the interconnection information upon accessing the interconnection information storage unit 104 and acquires an arithmetic operation parameter while accessing the arithmetic operation parameter storage unit 105 to determine a width W of the interconnection based on these values. That is, the width W of the interconnection is made to determine upon multiplying (current i)1/3 by the arithmetic operation parameter (constant), which current is caused to flow through the interconnection.
