    • A method of optimizing a portion of a circuit design for a target device can include identifying a critical region from a plurality of regions after an initial placement of the circuit design. The critical region can be defined, at least in part, by at least one input block and at least one output block. Blocks of the critical region can be relocated to different sites within the critical region. The method further can include evaluating the relocation of blocks of the critical region according to a cost function and continuing to relocate blocks and evaluate the relocation of blocks in the critical region until at least one exit criterion is met.
    • 优化目标设备的电路设计的一部分的方法可以包括在电路设计的初始放置之后从多个区域识别关键区域。 关键区域可以至少部分地由至少一个输入块和至少一个输出块来定义。 关键区域的块可以重新定位到关键区域内的不同位置。 该方法还可以包括根据成本函数评估关键区域的块的重新定位,并且继续重新定位块并评估临界区域中块的重定位,直到满足至少一个退出准则。
