Cadence Flow - Tools Setup

 

To the UMASS VLSI page

§            First you need to edit your ECS account .login and .cshrc and files.

1               Download this file vlsitools_setup.txt (modified 9/13/02) to your account by using wget.

 


(sloth) wget http://python.ecs.umass.edu/~cad/vlsitools_setup.txt

 

2               Open your .login file and the downloaded file with your favorite editor (eg. Emacs)

 


(sloth) emacs .login &
(sloth) emacs vlsitools_setup.txt &

 

3               Copy the first 6 lines from the vlsitools_setup.txt to the .login file

·        In emacs:

·        Right click and drag to select and copy a region

·        Right click in the destination file to place the cursor at the end of the .login file

·        Select Paste from the edit menu.

4               Copy all the lines from the 10th line of vlsitools_setup.txt to the end of your .cshrc file

 

 

§            Download the working directors and library links. vlsix.tar.gz

 


(sloth) wget http://python.ecs.umass.edu/~cad/vlsix.tar.gz


The cadence administrator has made modifications to the NCSU and VTVT library software in order for it to work properly. If you are doing research you should be aware of these modifications. Use at your own risk.

§            Change your working directory to /mnt2/username

 


(sloth) cd /mnt2/username

 

§            Move the vlsix.tar.gz file to your /mnt2/username workspace on sloth, if it's not there already.

 


(sloth) mv ~/vlsix.tar.gz .

 

 

§            Uncompress the file using gzip and tar

 


(sloth) gzip –d vlisx.tar.gz

(sloth) tar xvf vlsix.tar

 

Warning: This will create a directory called vlsix. If you have a directory by that name it will be overwritten.

§            Using the tools:

1               Source the .login and .cshrc files.

 


(sloth) cd ~

(sloth) source .login

(sloth) source .chsrc

 

 

You will never have to source the .login again as it is done when you log in.

 

§            Cadence creates some profile information automatically. If you have problems with the setup of various items you can copy my profiles to your directory.

1               The .cdsenv file is located in your home directory and it controls the scales used in the layout and schematic editor, the visible layers in your layer pallet, and various other small items. New users can use this directly by saving the file to your home directory as ".cdsenv" Older users should check their existing .cdsenv files.

2               The .cdsinit file sets up some initialization stuff. This version is the sample so if you have some custom initialization information you will need to add it to this file and save it as ".cdsinit" in your home directory.

3               The .cdsdoc.ini file helps your cdsdoc find all the help documentation. If you only show the AMS tools in the cdsdoc program copy this file to your .cdsdoc directory in your home directory.
