A wagering system is provided in which the payment on either side of a "neutral" bet, or center point, increases as the amount of win or loss diverges from the center point. The system is particularly applicable to bets placed in legalized bookmaking establishments, which set a line for sports betting and permit bettors to wager on either side of the line. In a preferred embodiment, the amount of win or loss increases arithmetically with the departure of the final result from the center point. The system also includes the potential for placing caps (maximums) on the win / loss multiples, and providing cushions (i.e., deviations proximate to the center point) before which the increased wins and / or losses commence.

A placer produces a global placement plan specifying positions of cell instances to be interconnected by nets within an integrated circuit (IC) by initially clusterizing cell instances to form a pyramidal hierarchy of blocks and generating an initial global placement plan specifying a position of each block at a highest level of the hierarchy. The placer then declusterizes the global placement plan by replacing the highest level blocks with their component blocks and then improves the routability of the global placement plan by iteratively moving specified block positions in directions and by distances dynamically determined by analyzing the global placement plan and an objective function having a total wirelength term and having a bin density term reflecting density of blocks in specified areas (bins) of the IC. The placer iteratively repeats the declusterization and routability improvement process until the global placement plan specifies positions of all blocks residing at the lowest level of the hierarchy, with weighting of the bin density term adjusted when necessary during each iteration of the routability improvement process to provide sufficient white space in each bin. The placer employs a look-ahead legalization technique to move low level blocks to legal positions during later iterations of the plan improvement process.

Placement or floorplanning of an integrated circuit is performed by constructing legal layouts at every level of a hierarchy of subsets of modules representing the integrated circuit, by scalably incorporating legalization into each level of the hierarchy, so that satisfiability of constraints is explicitly enforced at every level, in order to eliminate backtracking and post-hoc legalization.

A hierarchical method of legalizing the placement of logic cells in the presence of blockages selectively classifies the blockages into at least two different sets based on size (large and small). Movable logic cells are relocated first among coarse regions between large blockages to remove overlaps among the cells and the large blockages without regard to small blockages (while satisfying capacity constraints of the coarse regions), and thereafter the movable logic cells are relocated among fine regions between small blockages to remove all cell overlaps (while satisfying capacity constraints of the fine regions). The coarse and fine regions may be horizontal slices of the placement region having a height corresponding to a single circuit row height of the design. Cells are relocated with minimal perturbation from the previous placement, preserving wirelength and timing optimizations. The legalization technique may utilize more than two levels of granularity with multiple relocation stages.

As circuit sizes have increased, designs have become increasingly hierarchical. It is common for designs to have large numbers of macro blocks; many of these blocks are “soft,” and may have variable width and height. The present invention provides an alternate method to handle designs with large numbers of blocks. Rather than approaching them as expanded floorplanning, the problems are re-cast as traditional mixed size placement, and many macro blocks are treated as standard cells. Using existing mixed size placement tools, the superior reported are obtained. First, an effective “standard block design” methodology is provided. Second, new mixed size placement legalization algorithms that are more robust than the widely-used mixed-size Tetris algorithm is presented.

A method for resolving overlaps in the cell placement (placement legalization) during the physical design phase of an integrated chip design is described. This problem arises in several contexts within the physical design automation area including global and detailed placement, physical synthesis, and ECO (Engineering Change Order) mode for timing / design closure The method involves capturing a view of a given placement, solving a global two-dimensional area migration model and locally perturbing the cells to resolve the overlaps with minimal changes to the given placement. The method first captures a two-dimensional view of the placement including blockage-space, free-space and the given location of cells by defining physical regions. The desired global area migration across the physical regions of the placement image is determined such that it satisfies area capacity-demand constraints. The method also provides moving the cells between physical regions along previously computed directions of migration to minimize the movement cost. Also provided is an approximate method to model the movement of multi-row high cells.

A method placing items routing wiring pursuant to integrated circuit specifications to create an integrated circuit design. Once the initially placed design is legalized, rather that just starting wiring routing, the method identifies books in the integrated circuit design which contain blocked items. The method allows the routing process to be paused temporarily, and for the items to be moved to a certain extent. This movement process is controlled (limited according to signal power output by the associated books) so that the timing of the integrated circuit design is not affected by any such “mid-routing” movement. If the books do not have any blocked items, the process continues to route wires between the items and the books. If at any point before or during the routing of the wires it is found that the books do have blocked items, the process pauses the routing of the wires and performs any number of different processes to solve the blocked item situation (unblock the blocked items).
