ABSTRACT OF THE INVENTION A cable truss dome which is not triangulated is constructed from a plurality of cables under tension and compression members arranged in triangles having non-common sides. The cable truss dome is adapted for spanning large areas where the cables form a low shallow arch which supports a flexible membrane as a covering. The non-common vertex of the formed triangles are connec-ted to similarly placed vertical sides of other triangles through continuous nested tension rings.

A building structure has a plurality of elongated flexible compression arches or ribs to which a flexible membrane is operatively connected to span spaces between the arches in a folded pattern with the arches located at the apices of the folds and valleys formed between the apices. A plurality of cables are operatively associated with the membranes by prestressing and are located in the valleys formed between the arches in order to maintain the membrane in tension under substantially all load conditions so that the flexible arches are braced against buckling by the membrane. As a result, the flexible components of the structure cooperate to form a relatively rigid structural system capable of spanning relatively long distances for covering sports stadiums and the like.

Automated critical area allocation in a physical synthesized hierarchical design

A method, computer program product, and data processing system for efficiently performing automated placement of timing-critical unit-level cells in a hierarchical integrated circuit design is disclosed. In preparation for global optimization the entire unit at the cell level, macro-level cells are assigned a “placement force” that serves to limit the movement of the macro-level cells from their current position. Movement boundaries for each macro element are also defined, so as to keep the components in a given macro element in relative proximity to each other. Optimization/placement of the unit design is then performed, via a force-directed layout algorithm, on a “flattened” model of the design while respecting the movement boundaries. Following this “flattened” optimization, the placed “unit-level” cells are modeled as blockages and the macro elements are optimized individually, while respecting the location(s) of the blockages. This entire process is repeated until the optimization of the unit layout eventually converges.
