Fall 2010 ECE-E421 ADVANCED ELECTRONIC CIRCUIT
DESIGN
1 Objective
The objective of this lab is to help you to get started with the Cadence EDA software for Custom
VLSI design. The topics covered in this assignment include:
•Drawing an inverter in the Schematic Editor,
•Using Spectre do front-end simulation,
•Changing the schematic view for simulation purposes,
•Showing simulation results with signal waveforms.
2 Running Cadence
Cadence is one of the most widely used IC design software in the industry. Cadence includes many
packages for ASIC/SOC/VLSI design, some of which are used in custom IC design. In the content
of this course, you will learn low-level (transistor level) design tools of Cadence, especially Schematic
Editor for schematic design, Analog Artist for simulation environment and Spectre for simulation.
2.1 Preparing your PC for Cadence
First, you should open Xwin-32 software and login to your account (Refer to supplement materials).
When you login to the Solaris host, create a cds.lib file with the following lines (CHECK if they
are not there already):
SOFTINCLUDE $ SYSTEM CDS LIB DIR/cds.lib
DEFINE basic $ CDK DIR/lib/basic
DEFINE NCSU Analog Parts $ CDK DIR/lib/NCSU Analog Parts
