    • PROBLEM TO BE SOLVED: To provide a signal analysis device for obtaining a more accurate simulation result of the measuring signal of a substrate, and to provide a signal analysis method.
      SOLUTION: The signal analysis device comprises a signal difference calculation part 104 for calculating a difference between a signal measurement result and a signal analysis result; a signal analysis result correction part 105 for correcting to add the signal difference to an analysis result of a desired analysis point; an analysis extraction part 106; and a circuit analysis part 107. The signal analysis device enhances a product development efficiency, by adding the difference between the analysis result and the measurement result to the analysis result of the desired analysis point to correct the signal and accurately performing signal monitoring, in a development stage of a product, since the accuracy of the analysis result approximates signal waveform that is being generated on the actual product.

    • PROBLEM TO BE SOLVED: To reduce a change of a signal waveform, caused when reflection generated at a contact point with a probe is transferred to a circuit to be measured, concerning a signal measuring method of a circuit board or the like.
      SOLUTION: A circuit element for impedance matching or the like connected to a signal wire 106 is divided into two or more, and the probe 107 is brought into contact with a connection point, and the divided voltage of a signal is measured, to thereby cause reflection of the signal by the circuit element 101 adjacent to the circuit to be measured to be attenuate. Moreover, correction operation is performed, by using each impedance value of the circuit elements 101, 102 and the measured divided voltage, and the signal of a measuring point is led out.

    • PROBLEM TO BE SOLVED: To provide a design support system that supports operations of local placement designs of objects on a multilayer wiring board and streamlines an operation of verification of design consistency. SOLUTION: Series of dielectrics on opposite sides of a specific dielectric capable of having built-in parts are designated as a first part and a second part, respectively. A first support part 101 holds design information about the placement of objects mounted on the first part in a local design information storage part 141, manages it in response to commands given by a user via an input part 110 and displays the contents on a display part 120 to thereby support the design of the first part. A second support part 201 similarly supports the design of the second part. The first support part 101 and the second support part 201 hold design information about the placement of boundary objects mounted astride both parts in boundary design information storage parts 142 and 242, respectively, and cooperatively and synchronously display the contents on the display parts 110 and 210, respectively.
