ABSTRACT:
A computer-aided design tool generates a layout for a passive device, such as a resistor or a capacitor, to be incorporated into an integrated circuit. The layout is based on a model describing the passive device as being formed by a variable number of interconnected instances of a device unit, such as a resistor segment or a capacitor block. User-supplied Input parameter values control the number of instances of the device unit included in the passive device layout, the relative positions of the device unit instances, and characteristics of their internal layouts. The tool also generates a display of a representation of the passive device layout and provides a graphical interface enabling the user to modify various aspects of the passive device layout by altering its displayed representation.
