SynthesisOne of the goals of clock tree synthesis in ASIC design flow is skew minimization. There are several approaches used in traditional clock tree synthesis tools to achieve this goal. However, many of the approaches create a large number of clock-buffer levels while others res...
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...

Mesh clock network synthesis: (a) postmesh buffer insertion, (b) mesh grid construction, (c) mesh driver insertion, and (d) premesh tree synthesis. Full size image Figure3illustrates the overall synthesis flow of a mesh clock network; we synthesize a mesh clock network in a bottom-up mann...
The potential benefits of STI in ASIC design are evaluated using a standard industrial VLSI-CAD flow including sleep-transistor insertion and routing after the clock synthesis and place-and-route of the benchmark circuits. The results show that the clock tree leakage power is reduced by 19–32%...
A method for low power clock tree synthesis using buffer insertion, removal and resizing for high-speed VLSI design is proposed. A developed tool can be embedded in the existing clo
A clock tree synthesis (CTS) tool determines how to position a hierarchy of buffers for fanning out a clock signal to clocked devices (“sinks”) within an integrated circuit (IC). The tool first clusterizes the sinks and places a lowest level fan-out buffer near each cluster. The tool ...
