===== Introduction =====




===== Cadence DFII documentation =====

Super protetta, non si puo' pubblicare/divulgare! 



cdsdoc is no longer available! It has superseded by the Cadence Help. Type cdnshelp to acces the help system

The entire Cadence IC documentation is accessible through the ''cdnshelp'' executable
located in 


''<sub>$IC_DIR/tools/cdnshelp/bin/cdnshelp</sub>''

In order to be able to launch the executable modify your search path in your ''.cshrc'' file as follows:
you can modify your search path

<code>
set path = ( $IC_DIR/tools/cdnshelp/bin $path)
</code>

<code>
source .cshrc
</code>

<code>
cdnshelp &
</code>

cdnshelp is the **help document browser** for Cadence. It opens .html files located in the install directory for each tool




La documentazione di **Cadence IC** e' in 

''<sub>/usr/cadence/IC_6.1.X/doc</sub>''


<code>
cd ~/cadence
mkdir doc
</code>

===== 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

<code>
mkdir ~/scratch
cd  ~/scratch
mkdir tutorials
</code>


<code>
cd tutorials
mkdir data doc libs logs models src tmp 
</code>


Poi per runnare un cadence vanilla basta fare il source di

<code>
source /usr/local/config/cds_config/CdsIC_615.rc
</code>

You might retrive a ''MANPATH: Undefined variable'' error.

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

<code>
Execute Global CADENCE IC configuration version 6.1.5 HotFix 615
	Release 13 Jan 2012
</code>


<code>
which virtuoso
/usr/cadence/IC_6.1.5/tools/dfII/bin/virtuoso
</code>

<code>
xterm &
</code>

===== 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 

<code>
cd ~/scratch/tutorials
virtuoso [options] &
</code>

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

<code>
virtuoso -h [-help]
</code>

<code>
virtuoso [-log ../logs/tutorial_1.log] &
</code>

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.

{{:vlsi:command_interpreter_window.png?750}}


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

<code>
$IC_DIR/tools/cdnshelp/bin/cdnshelp &
</code>

{{:vlsi:cadence_ic_615_help.png}}


===== 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.

{{:vlsi:exit_virtuoso.png}}

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


===== Licenses =====

You can view the list of Cadence licensed tools within Cadence itself from the Command Interpreter Window (CIW), 
simply look in 

**CIW => Options => License...**





===== Available licenses =====

a tiered architecture (L/Xl/GXL), se viene checked-out a higher license automaticamente sono licenziati anche i tools inferiori 

All Cadence software requires Cadence licenses!

Tutto e' sotto licenza! E c'e' un PC che fa solo da **license server**

You can use the Software Product License Management form to track token license activity.

**CIW => Options => License ...**

You can check the state of the licence server or the number of available licences
if you run into trouble opening a program.

The lmstat command can be used to track token license activity from the command line


<code>
lmstat [-help]
</code>

To view the number of available licences for each program,

<code>
lmstat -a
</code>


''CDS_LIC_FILE'' => punta al server

''LM_LIC_FILE''
