Abstract: Aspects of the invention include methods, systems, and computer program products for integrated circuit development using cross-hierarchy antenna condition verification. A method includes obtaining a design of a hierarchical macro distributed between multiple files for an integrated circuit and analyzing, by a design verification tool, a route between at least one child macro and at least one pin of the hierarchical macro as defined in the files. The method further includes determining, by the design verification tool, a plurality of connection characteristics of the at least one child macro and the at least one pin forming the route and calculating, by the design verification tool, an antenna condition for the route based on the connection characteristics. The design of the hierarchical macro is adjusted to remove a violation of an antenna rule based on determining that the antenna condition of the route violates the antenna rule.

Abstract: Articles, such as plastic parts, having the appearance of a naturally-occurring material such as wood or leather are formed by the techniques of (1) providing a plurality of grooves in a surface of the article, (2) applying a surfactant to the surface of the article, and (3) applying one or more color solutions to the surface of the article. The article may be a solid substrate, a part or a film. A topcoat is preferably applied to the surface of the article. The techniques include controlling movement of an applicator implement for applying the surfactant and color solutions to the surface of the substrate, and controlling movement of a saturator tool for modifying and synthesizing the surfactant and color solutions on the surface of the part and permeating the surfactant and color solutions into the plurality of grooves.

Abstract: A track having spaced, parallel edges, including a plurality of adjacent curves facing in different directions and connections between the curves, around which a frame carrying an object, such as simulating a racing car, a greyhound, a horse, a camel or the like, is moved by gravity when the track is tipped. An inner panel has an outer contour providing the inner edge of the track, while an outer panel has an inner contour providing the outer edge of the track. The frame on which the object is mounted carries a pair of wheels engaging both the bottom and the top of the track at each side. The frame also carries a pair of circular, rotatable ball bearings mounted for rotation in the plane of the track panels and engageable alternatively with the opposed edges of the track for guiding the object around the track. The spacing between the track edges is slightly greater than the diameter of the ball bearings, to provide clearance.
