Project CAD Tools

Setup Cadence See Cadence Tool setup, NCSU ver 1.2. Note item 5, the upgrades to the Mentor Graphics link. You will need CAD tools for the project. For tutorials on how to use Cadence, see the section on Tutorials on the Setup webpage. A specific tutorial from NMSU is given here NMSU Analog Cadence Tutorial

To look at the online (unix) Cadence help system, open up a browser - type (at cmd prompt) mozilla&
and then type cdsdoc&
Click on a topic and it should show up in the browser window.

Cadence VerilogA models of data converters and other analog blocks can be found by defining a library in your
cds.lib file as

CAD tool use for chip design

One goal of the project work is to get familiar with design flows for chip design. In design, it is helpful to know how to interact with the chip fabrication and testing companies. Also, in EE721 (spring), group chip design projects may send out a chip design for fabrication.
A good source for how to deal with chip fabrication companies (foundries) is at: Chip fabrication broker
