    • A physical synthesis tool for dock optimization with local clock buffer control optimization is provided. The physical synthesis flow consists of delaying the exposure of clock routes until after the clock optimization placement stage. The physical synthesis tool clones first local clock buffers. Then, the physical synthesis tool runs timing analysis on the whole design to compute the impact of this necessarily disruptive step. After cloning local clock buffers, the physical synthesis tool adds an extra optimization step to target the control signals that drive the local clock buffers. This optimization step may includes latch cloning, timing-driven placement, buffer insertion, and repowering. The flow alleviates high-fanout nets and produces significantly better timing going into clock optimization placement. After placement, the physical synthesis tool fixes latches and local clock buffers in place, inserts clock routes, and repowers local clock buffers.
    • 提供了一种用于通过本地时钟缓冲器控制优化进行码头优化的物理综合工具。 物理合成流程包括延迟时钟路由的曝光,直到时钟优化放置阶段为止。 物理综合工具克隆了第一个本地时钟缓冲区。 然后,物理综合工具对整个设计运行时序分析,以计算这一必然破坏性步骤的影响。 在克隆本地时钟缓冲器之后,物理综合工具增加了一个额外的优化步骤来对驱动本地时钟缓冲器的控制信号进行目标。 该优化步骤可以包括锁存克隆,定时驱动放置,缓冲器插入和重新供电。 该流程减轻了高扇出网络,并显着提高了进入时钟优化布局的时间。 放置后,物理综合工具将锁存器和本地时钟缓冲器固定到位,插入时钟路由并释放本地时钟缓冲区。

    • A method, system, and computer program product for solving a network traffic congestion problem are provided in the illustrative embodiments. Using an application executing using a processor and a memory in a data processing system, a congested network route section is selected from a set of congested network route sections. A set of congesting devices is selected, where the set of congesting devices causes congestion in the selected congested network route sections by using the selected congested network route section. A vacancy data structure corresponding to the selected congested network route section is populated. A subset of the set of the congesting devices is selected. The subset of the set of the congesting devices is rerouted to a candidate network route section identified in the vacancy data structure.
