OVERVIEW

The workshop starts out with a high level introduction to IC Compiler’s graphical user interface, during which you will learn about the 3 core commands, place_opt, clock_opt and route_opt as well as the more targeted atomic commands for more specific needs.

You will learn the details of design and timing setup, including setting up all physical and logical libraries, importing various design formats and floorplans, and setting the design up for proper timing analysis.

The workshop goes in-depth into using IC Compiler to perform placement, power optimization, scan optimization, clock tree synthesis and routing operations, including interleaved logic optimizations. You will also learn how to perform Design for Manufacturing tasks in IC Compiler, including antenna fixing, via doubling, metal filling and critical area optimization.

Another unit is dedicated to the topic of the new Multi Scenario capabilities, including how to apply SDC constraint files and operating conditions and perform analysis and optimization in parallel. The unit will also show you the advantages of using on-chip variation mode.

The class will explore the new Design Planning features in IC Compiler, which support full flat floorplanning including automatic macro placement, power network synthesis and analysis, and prototype route and optimization.

The workshop is accompanied by comprehensive hands-on labs, which provide an opportunity to apply all concepts covered during the lectures.
