VSD - Clock Tree Synthesis - Part 2

Overview

This course is a follow-up course of "VLSI Academy - Clock tree synthesis - Part 1". So its highly recommended to go through Part 1 of clock tree synthesis

Clock is a critical part of any VLSI chip, and this course takes you to the advanced level of building a clock tree from scratch for millions of flop.

While we plan to add some experimental videos and courses very soon, as a supplement, this one has real time examples and problems that you see on a real chip, and even solutions to those problems

The course is structured in below format:

  • Introduction
  • Clock tree optimization checklist
  • How to build clock tree for uneven spread of clock end-points
  • Power aware clock tree synthesis
  • Static timing analysis with real clocks
