Abstract: In an electronic circuit design system, dynamic visual guidance for relative placement of mutually paired electronic components, such as a bypass capacitance portion and a power pin in a power domain, is provided. A first, selected component is adaptively paired with one of a plurality of second components eligible for pairing with the first component, according to predetermined pairing criteria such as proximity criteria. A mutual placement zone between the paired components is generated to define a locus of valid placement locations of the paired first and second components one with respect to the other according to predetermined placement criteria therefor. Visual indicia to represent the mutual placement zone is generated, thereby providing visual guidance to reposition the first component.
