  • System and method for designing a printed-circuit board
    Patent number: 5559997
    Abstract: According to the printed-circuit board of the preset invention, the circuit modification unit 120 adds a noise reduction component, based on circuit board information inputted to the design information input unit 106. Then, the layout unit 132 sets a layout after the design rule generation unit 133 generates a design rule. The rated value modification unit 124 determines rated values of noise reduction components in accordance with the layout. Thus, design rule generation, noise reduction component addition, and rated value determination are automatically performed to satisfy the electric characteristics of evaluation targets. Consequently, interactive process in designing is reduced and the efficiency of designing can be realized.
