Disclosed are techniques for implementing three-dimensional or multi-layer integrated circuit designs. These techniques identify an electronic design and a plurality of inputs for implementing connectivity for the electronic design. Net distribution results may be generated at least by performing one or more net distribution analyzes. A bump in a bump array may then be assigned to a net that connects a first layer and a second layer in the electronic design based in part or in whole upon the net distribution analysis results.

Methods, systems, and computer program product for implementing three-dimensional integrated circuit designs

Disclosed are mechanisms for implementing three-dimensional operations for electronic circuit designs. These mechanisms identify a cross-layer layout portion by identifying a first electronic design as an editable layout portion and a second electronic design as a selectable and non-editable layout portion in a single window, determine a ruler by identifying or generating the ruler for a three-dimensional operation across the first electronic design and the second electronic design on different layers, identify one or more starting targets and one or more end targets within an aperture at least by determining the one or more starting targets and one or more end targets based in part or in whole upon a location of the aperture and the one or more rulers, and perform the three-dimensional operation at least by manipulating a plurality of shapes in the cross-layer layout portion based in part or in whole upon the one or more rulers.

Display of measurements in a graphical design on a computer system. In one aspect, shapes are displayed in an image, and a definition of a defined area of the image is received. One or more measurements are determined for one or more of the shapes displayed within the predefined area, the one or more measurements determined automatically without a user designating endpoints for the measurements. The one or more measurements are displayed as being associated with the one or more shapes.

Generation, display, and manipulation of measurements in computer graphical designs

Graphical viewing of shapes and descriptive information in displayed graphical images. In one aspect, shape information is displayed in a graphical interface using a computer system and includes causing a display of an image and one or more shapes in the image, and causing a display of a cursor. Labels are also displayed, each of the labels associated with a different one of the displayed shapes. The plurality of labels are displayed within a predetermined zone relative to a displayed cursor, and wherein no labels are displayed outside of the zone.
