However, most existing power-aware clock-tree minimization algorithms optimize power on the basis of flip-flops alone, which may result in limited power savings. To achieve a power and timing tradeoff, this paper investigates the pulsed-latch utilization in a clock tree for further power savings....
clock spine阶段主要实现H-Tree的搭建,即芯片层次的H-Tree和模块内部的H-Tree,芯片层次的H-Tree需要借助TMAC实现,模块内部的H-Tree需要首先对内部寄存器进行放置约束,然后以mesh buffer为根节点做H-Tree;clock mesh主要完成时钟网的布局、anchor pin的设定以及局部模块驱动器(Mesh buffer)的放置。 2.1 Clock Spine的...
Intuitively, by sharing sleep transistor, the virtual ground voltage (VM in Fig. 5) increases in comparison to when Post synthesis clock tree leakage power optimization In the previous section, we have shown that STI inherently reduces the leakage power dissipation of a group of clock buffers by...
