摘要： Cells are placed into an integrated circuit floorplan by creating clusters of cells in modules, each cluster being composed of cells in a path connected to at least one flip-flop in the module, or of cells that are not in a path connected to any flip-flop. Regions are defined in the floorplan for placement of modules, and the clusters are placed into optimal locations in modules and placing the modules into optimal locations in the regions. The coordinates for the wires, modules and clusters are selectively recalculated. The clusters are moved in the floorplan for more uniform density, and the modules are assigned to regions based on module coordinates.

摘要： Objects are placed in a rectangle and their coordinates of the objects and are adjusted to establish a substantially uniform density of objects in the rectangle. The evaluation of coordinates is performed by placing the wires between cells coordinates and adjusting the cell coordinates to connect the cells to the wires. The substantially uniform density is achieved by dividing the rectangle into first and second rectangles having equal free areas and into third and fourth rectangles having equal areas of objects. The coordinates of the objects are adjusted based on boundaries between the first and second rectangles and between the third and fourth rectangles.

摘要： The present invention provides a method for mapping a netlist of an integrated circuit to a design. The method includes steps as follows. Chaos algorithm is used to obtain most favorable places in the design for cells from the netlist. Kuhn's algorithm is utilized to assign each cell of the netlist a cell in a template so that, for each cell of the netlist, its place in the template is as close as possible to its place obtained by the chaos algorithm. Simulating annealing optimization technique is applied to reduce a sum of wire length of the design.

摘要： Boolean circuits are designed with minimal depth by calculating the depth of an existing circuit. Those subtrees having a non-regular root cell (i.e., cells having other than one child or having a child of a type different from the cell) are balanced by constructing a new subtree. The cells are then iteratively transformed with parent and/or grandparent cells to reduce the depth of the circuit. The transformation may include balancing the subtree to make the parent cell the same type as the selected cell, or by creating a new cell as parent to the selected cell.
