  • Scripted, hierarchical template-based IC physical layout system
    Patent number: 7178114
    Abstract: A computer-aided design tool for automatically generating a layout for an electronic device to be formed by a set of objects implemented within an integrated circuit, receives input from a user defining a device template specifying shapes, dimensions and relative positions within the layout of the objects forming the device. Some of the object dimensions and/or relative positions are specified as functions of values of input parameters to be supplied by the user. When the user supplies the input parameters, the CAD tool evaluates the functions to determine the object dimensions and/or positions that are functions of the input parameters and then generates a layout for the electronic device wherein object shapes, dimensions and relative positions are as specified in the device template and consistent with the function evaluations.
