Launching Cadence

by Dr. Rishi Todani & Dr. Ashis Kumar Mal

Here, I shall illustrate how to launch Cadence icfb tool in VLSI lab at NIT Durgapur.

Cadence design tools like Virtuso typically install on an rpm based linux distribution. Although the company suggests Redhat Enterprise Linux, many people have successfully run Virtuoso in other rpm based distos like Fedora, CentOS and SuSe Linux.

For first time users, some necessary files are needed to be copied from the server to the user terminal. We would be using UMC 180 nm technology, hence the name of the folder which will be copied. Open a terminal and issue the following commands.

$> scp -r cadmgr@nitdgp01:~/umc180 ./

then provide the password for cadmgr when prompted.

This will copy a folder umc180 into your home folder which contains the necessary to launch Cadence.

If you wish to copy the necessary UMC files to a folder name of your choice, then issue the following commands at the shell promt.

$> scp -r cadmgr@nitdgp01:~/umc180/ ./yourfolder/

(replace yourfolder by a folder name of your choice)

All the necessary files will be copied to a folder called yourfolder in your home directory.

To launch Cadence, issue the following commands in the terminal.

$> tcsh
$> cd yourfolder
$> source cshrc.cadence
$> icfb &

The cshrc.cadence filename may vary from lab to lab. This cshrc file typically sets the paths and the environments for cadence tools.
