METHOD FOR DESIGNING ELECTRONIC SYSTEM

摘要

When a large scale integrated circuit chip (LSI), a package (PKG), and a printed circuit board (PCB) are designed independently in parallel in the design of an electronic system, electric characteristics are sometimes not satisfied near the end phase of the design.  For this reason, the design procedures of respective element components (components such as the LSI, the PKG, and the PCB) are determined before the total design of the electronic system is started, and after the allocation of resources to an element component to be preferentially designed is determined, the design of the remaining element components is started.  Therefore, using information (8s-11s) relating to the design of the board as input data, the basic wire distribution (18) of the board is determined by a prediction function for predicting the wire distribution of the board, and the basic wire distribution is outputted.
