Computer-Aided Preliminary Layout Design of Customized MOS Arrays

Abstract: One of the most perplexing problems confronting device designers utilizing MOS technology is the development of an effective layout design methodology. This paper describes a versatile layout design scheme for customized digital-type MOS arrays utilizing four-phase clocking schemes (ratioless logic). The analytical characterization of this layout design scheme is defined through the introduction of p-order and m-order indices. The p-order indices are assigned to members of the Boolean equation set that define the relative placement of their mechanization areas (p-diffusion structures) on the MOS array. The m-order indices are assigned to members of the term set that define their relative placements within parallel metalization channels on the MOS array. The underlying variables influencing the algorithmic derivation of quasi-optimal p-order and m-order assignments are also discussed.

Graphical Layout System for IC Mask Design

Abstract: The Fairchild graphical layout system is a design tool for the layout and production of masks for large-scale integrated circuits. Its purpose is to reduce the time delay from the specification of a circuit design in schematic form to the production of a set of masks to be used in the manufacturing process. The system operates on an IBM 1130 computer with 16K 16-bit words of core memory. A Sanders display system built to Fairchild specifications makes possible rapid graphic man-machine interaction. An entire design may be carried out at the display or portions of it may be entered through punched cards. Final output consists of masks cut on a Calcomp plotter, line drawings, and/or digital images of the design which may be saved for later use and modification, or for output on other media (e.g., reticle generators). The use of a grid system for determining coordinate positions together with software windowing and scaling has produced a layout design package that is easy to use and provides rapid response to user requests with a relatively small low-speed computer. The graphical layout system produces circuit layouts with resolutions that are an order of magnitude greater than the resolution of the CRT display.

A Demonstration of Magazine Page Layout Using a Graphic Display Terminal

Abstract: This paper describes an application of interactive graphic display terminals to magazine composition. The techniques discussed are being used in a demonstration system designed to evaluate a proposed computer typesetting system. The proposed system uses on-line terminals to prepare, edit, arrange and filmset text for magazine pages. The demonstration system utilises off-line text preparation, editing on an IBM 2250 graphic display and filmsetting on a Harris-Intertype Fototronic-CRT. Only the editing on the graphic display is discussed in detail. The display is used to draw diagrams showing the text layout on the page. The paper describes in detail the drawing techniques, data storage and the algorithm to justify type into areas drawn on the graphic display.

Abstract: One of the most perplexing problems confronting device designers utilizing MOS technology is the development of an effective layout design methodology. This paper describes a versatile layout design scheme for customized digital-type MOS arrays utilizing four-phase clocking schemes (ratioless logic). The analytical characterization of this layout design scheme is defined through the introduction of p-order and m-order indices. The p-order indices are assigned to members of the Boolean equation set that define the relative placement of their mechanization areas (p-diffusion structures) on the MOS array. The m-order indices are assigned to members of the term set that define their relative placements within parallel metalization channels on the MOS array. The underlying variables influencing the algorithmic derivation of quasi-optimal p-order and m-order assignments are also discussed. This preliminary layout design methodology is then related to the computer-aided design environment. Two computer programs, named P-ORDER and M-ORDER, that comprise the computer-aided design environment are briefly described. A simple example is also presented to illustrate the complementary relationships that exist between the device designer and computer within the computer-aided design environment. Computer inputs and outputs for this simple problem are presented to stress the minimal input requirements and the pictorial characterizations of computer-synthesized solutions, which are essential ingredients to cost effective computer-aided design applications.
