Tutorials:Cadence:Main

This manual is intended primarily for students in CSE463: Digital Integrated Circuits and Architecture offered at Washington University at St. Louis. Basic knowledge of how CMOS transistors operate is required. The main goal of this manual is to teach you to use the Cadence Design Environment to design and test digital CMOS circuits. The design toolkits are based on NCSU PDK 1.6 and Cadence IC 6.1 base.

This manual will walk you through all the necessary steps for designing and testing an inverter. First, we are going to create a schematic for the inverter. We, then, create a symbol for the inverter and test the transient and DC characteristics of this inverter using Analog Artist Simulator. Next, we are going to create a layout for the inverter and test the transient and DC characteristics on the layout of the inverter. Finally, we are going to create a behavioral view for the inverter in Verilog XL and simulate its behavior.

Use the menu on the left to guide yourself through the various design examples.
