Course Description
This course describes the tools and methods of developing parameterized cells (PCells) in the SKILL® programming language, which is the Virtuoso® Design Environment extension language. A primary focus of the course is dedicated to an introduction and investigation of relative object design (ROD), a new technology providing powerful, flexible procedures for defining simple and complex layout objects and their relationships to each other.
Based upon a firm foundation in relative object design, PCell development will be explained in stages, beginning with creation of sizeable transistors and evolving into a fully parameterized inverter layout.
The SKILL and PCell IDE are introduced and used in the course to highlight the improvements to developing and debugging SKILL code and PCells.
How to design and test a Fluid PCell is covered and example code is provided. Adding CDF for PCell parameters and a discussion of the IC 6.1 connectivity model and example SKILL code is included.
This course places heavy emphasis on lab exercises.
Learning Objectives
