    • 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).
    • 一种根据集成电路规范布置布线的方法来创建集成电路设计。 一旦初始放置的设计合法化,而不仅仅是启动布线路由,该方法可以识别集成电路设计中包含阻塞项目的书籍。 该方法允许临时暂停路由进程,并将项目移动到一定程度。 该移动过程被控制(根据相关书籍的信号功率输出而限制),使得集成电路设计的时序不受任何这种“中间路由”移动的影响。 如果这些书没有任何封闭的物品,该过程将继续在物品和书籍之间布线。 如果在电线路由之前或期间的任何一点,发现这些书籍确实有阻塞的项目,该过程将暂停线路的路由并执行任意数量的不同进程来解决阻塞的项目情况(解除阻塞的项目) 。
