Introduction

Setting up the UNIX evironment

If needed, revisit the UNIX tutorial before proceeding.

Never run Cadence executables from your home directory! Cadence creates many extra files/directories that will clutter your home directory. Create indeed a main directory cadence in your home and another subdirectory tutorials in order to keep all the files that will be created:

Create a main ~/scratch directory if you did not yet 

mkdir ~/scratch
cd  ~/scratch
mkdir tutorials
cd tutorials
mkdir data doc libs logs models src tmp

Poi per runnare un cadence vanilla basta fare il source di 

source /usr/local/config/cds_config/CdsIC_615.rc

You might retrive a MANPATH: Undefined variable error. 

setenv MANPATH ""
source /usr/local/config/cds_config/CdsIC_615.rc

Running Cadence Virtuoso

All Cadence IC executables have been integrated into a single executable called virtuoso. To run the Cadence IC framework move into the design directory and 

cd ~/scratch/tutorials
virtuoso [options] &

at the command line. It's possible to launch virtuoso with some additional command line options. You can retrieve more information about them using: 

virtuoso -h [-help]
virtuoso [-log ../logs/tutorial_1.log] &

Please, start the task into the background by adding the ampersand symbol & at the end of the command. In such way you will get the command prompt back right away. Otherwise you will no more be able to type commands in the xterm window.

The software may take some time to load. After the first Cadence splash screen has been shown the Command Interpreter Window (CIW) and a What's New window will appear.

Look at the information contained in the log window.

For more details and documentation about the CIW left click CIW ⇒ Help ⇒ Using the CIW.
The entire Virtuoso platform documentation can be accessed though CIW ⇒ Help ⇒ Virtuoso Documentation or entering at the comamnd line 

$IC_DIR/tools/cdnshelp/bin/cdnshelp &

Quitting the session

To quit the Cadence session left click on

CIW ⇒ File ⇒ Exit…

A confirmation dialog box should appear. Left click OK to quit Cadence or Cancel to resume.

A Save All window may appear. Left click OK to save design data.
