    • A task-based multi-process design synthesis methodology relies on a plurality of child processes to assist a parent process in performing optimizations on an integrated circuit design. Objects from an integrated circuit design are grouped into subsets and assigned to child processes, with each child process performing a transform on each of the objects in the subset assigned to that child process and determining which of the objects in the subset are candidate objects for which performance of the transform has been successful. The child processes then notify the parent process of those objects that qualify as candidate objects, so that the parent process only has to perform the transform on the candidate objects, thereby relieving the parent process from the overhead associated with performing the transform on non-candidate objects for which the transform has been determined by the child processes as not being successful.
    • 基于任务的多进程设计合成方法依赖于多个子进程来辅助父进程对集成电路设计进行优化。 来自集成电路设计的对象被分组成子集并被分配给子进程,每个子进程对分配给该子进程的子集中的每个对象执行变换,并且确定该子集中的哪些对象是候选对象 变革的表现已经取得成功。 然后,子进程通知那些符合候选对象的那些对象的父进程,以便父进程只需对候选对象执行转换,从而将父进程从与非候选对象执行转换相关的开销中解除 子进程已将该转换确定为未成功的对象。
