INSTALLATION

(0) Login in to your ECE account.

(1) First you must prepare your account for Synopsys by editing ~/.cshrc.
Please add the following lines at the end of the file:

#### Synopsys CAD Tools

set path = ($path, /opt/Synopsys/Simulation/sparcOS5/sim/bin)
setenv LM_LICENSE_FILE /opt/Synopsys/Synopsys_Common_Licensing/admin/license/key
setenv SYNOPSYS /opt/Synopsys/Simulation
setenv SYNOPSYS_SIM /opt/Synopsys/Simulation

source /opt/Synopsys/Simulation/admin/setup/environ.csh


Then you save the file and quit the text editor.

(2) On your terminal, type command "source ~/.cshrc" for the changes to take effect.
This change will allow you to use the Synopsys analyzer and simulator tools.

(3) The next step is to create a project directory where you will store all your
vhdl files. Synopsys requires that preference files be kept in the same directory
as the vhdl files. Preferences are stored in two files: .synopsys_vss.setup and
.synopsys_dc.setup. You can find them in directory ~/yyzhang. 
Copy both files to your directory:

> mkdir [your vhdl directory]
> cd [your vhdl directory]
> cp ~yyzhang/.synopsys_vss.setup  ~yyzhang/.synopsys_dc.setup .

Please note that the dot at the end of the last command is the UNIX symbol
for the current directory you are in (it is NOT a period).
