    • A number of virtual regionalization lines are laid out across a chip such that the virtual regionalization lines delineate a plurality of regions on the chip. One of the plurality of regions on the chip is designated as a master region and each of a remainder of the plurality of regions on the chip is designated as a duplicate region. A number of functional blocks are placed in the master region. Each of the functional blocks is replicated in each duplicate region by placing each functional block in each duplicate region so as to be symmetric with the corresponding functional block in the master region about the virtual regionalization lines. Wires are routed in the master region. The wires routed in the master region are replicated in each duplicate region so as to be symmetric about the virtual regionalization lines.

    • Some embodiments of the present invention provide a system that routes nets over circuit blocks in a hierarchical circuit design. During operation, the system can receive a set of circuit blocks. At least some terminals of the circuit blocks may be desired to be electrically linked together using a net which is expected to be routed over one or more circuit blocks. The system may divide an area associated with a block (e.g., an area in a metal layer which is situated above the block) into a set of tiles. Next, the system may assign costs to at least some of the tiles in the set of tiles. The system can then use the costs during routing. Note that using the costs of the tiles during routing makes it more likely that buffers can be used wherever required to meet slew and timing requirements.
    • 本发明的一些实施例提供一种在分层电路设计中将网络路由到电路块上的系统。 在运行期间,系统可以接收一组电路块。 电路块的至少一些端子可能期望使用期望在一个或多个电路块上布线的网电连接在一起。 系统可以将与块(例如,位于块之上的金属层中的区域)相关联的区域划分成一组瓦片。 接下来,系统可以将成本分配给该组瓦片中的至少一些瓦片。 然后,系统可以在路由期间使用成本。 请注意,在路由期间使用瓦片的成本使得缓冲区更有可能在需要满足压缩和时序要求的地方使用。

    • A mechanism is disclosed for determining pin assignments in an integrated circuit. More particularly, the mechanism involves accessing design information for the integrated circuit. The design information includes a floorplan that sets forth an arrangement of blocks in the integrated circuit and timing information for interconnections between the blocks. Based on the timing information, routing information is determined for the interconnections between the blocks. The routing information includes physical routes and physical pin placements for the interconnections.
