Abstract
A method of automatically generating a custom device layout includes the step of specifying a device type and an associated set of device parameters. The device type is then matched to a selected cell in a cell library. Physical layout regions of the selected cell are then selectively modified in accordance with the device parameters. The physical layout regions may also be selectively modified in accordance with technology design rules in a design rule library. The physical layout regions of the selected cell are then drawn.
