Abstract

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.
