  • Publication number: 20110210453
    Abstract: When an electronic system is designed, then if an integrated circuit chip (LSI), a package (PKG), and a printed circuit board (PCB) are designed separately and in parallel, it will be found near the end of the design process that a satisfactory electrical characteristic is not achieved. Therefore, a design procedure of each part (e.g., an LSI, a PKG, a PCB, etc.) is decided, and allocation of resources to a part which is designed with a higher priority is decided, and thereafter, the other parts start to be designed. Therefore, a basic interconnect distribution for a circuit board is calculated based on a prediction function for predicting an interconnect distribution for the circuit board using design information of the circuit board as input data, and is output.

  • Publication number: 20060237852
    Abstract: In the LSI design stage, areas indicating the circuits that handle a minute signal are formed as wiring excluding area patterns. The coordinates of the wiring excluding area patterns in a state that the LSI chip is flipped are calculated, and the substrate design tool is caused to recognize such coordinates. No wiring is provided in the recognized wiring excluding areas when the substrate wirings are designed by the substrate design tool. As a result, the electric coupling between the substrate wirings and the minute signal circuit can be suppressed, and also a malfunction of the circuit can be prevented.
