In this work, we study the concept of a generalized H-tree – a topologically balanced tree with an arbitrary sequence of branching factors – and propose a dynamic programming-based method to determine optimal clock power, skew and latency, in the space of generalized H-tree solutions.

2024年11月30日 · Discover the main types of clock tree structures, including H-tree and balanced tree designs, and learn how they optimize signal distribution in integrated circuits.

2018年12月25日 · In this paper, we study the concept of a generalized H-tree (GH-tree)-a topologically balanced tree with an arbitrary sequence of branching factors-and propose a dynamic programming-based method to determine optimal clock power, skew, and latency, in the space of GH-tree solutions.

所谓Flexible H-Tree，简而言之就是Cadence的后端工具Innovus的一个功能，可以使用户更方便快捷地实现H-Tree结构的时钟树综合。 在此之前，除了传统CTS之外，包括上述所有的clock手法都需要用户做大量的工作，包括时钟规划、脚本编写、结果确认与改善，虽然可以一定程度上实现自动化，但仍然无法避免大量的手动工作。 而Flexible H-tree这种功能可以通过简单地定义几个 …

The H tree (so called because its repeating pattern resembles the letter "H") is a family of fractal sets whose Hausdorff dimension is equal to 2. They can be constructed by starting with a line segment of arbitrary length, drawing two shorter segments at right angles to the first through its endpoints, and continuing in the same vein, reducing ...

2012年11月25日 · The H-tree got his name because of its repeating pattern which looks like the letter "H". It is also called H-fractal, it's a space-filling curve with a Hausdorff dimension of 2. A binary tree is a tree where each node has no more than two child nodes.

An H-tree is a space-efficient tree-layout technique for balanced binary trees. The first thing you probably gathered from that sentence is that H-tree is some theoretical mathematical or computer science concept.

本文探讨了常见的时钟树结构，包括H Tree、Multi Point CTS (Multi Source CTS) 和 Clock Mesh。Multi Source CTS在时钟网络优化中展现出优势，因其共享公共路径特性。Clock Mesh结构提供了更好的路径共享。

In this paper, we present a dynamic programming based approach to synthesize a minimum cost buffered H-tree clock distribution network. Our cost functions are a weighted sum of power and jitter, and a weighted sum of power and end-to-end delay of the distribution network.
