How do I check or manually set the environment variables for Xilinx design tools?
NOTE 1: If you are not sure what to set your environment value to, try "1" or "TRUE".
NOTE 2: Xilinx design tools must be closed and restarted for the environment variables to be used.
NOTE 3: To disable the variable, setting to "0" or "FALSE" does not always work. You should remove the variable.
Solution 1
To set in Linux / Solaris (csh/tcsh shell)1. Use the command "setenv VARIABLE value"
2. Test whether it worked by using "echo $VARIABLE"
For example::
setenv Xilinx \programs\Xilinx
To unset in Linux / Solaris (csh/tcsh shell)
1. Use the command "env -u VARIABLE"
2. Test whether it worked by using "env"
For example::
env -u Xilinx
Linux / Solaris (sh/bash shell)
1. Use the command export VARIABLE = value
2. Test whether it worked by using "echo $VARIABLE"
For example:
export Xilinx = \programs\Xilinx

For a single Project Navigator sessionOn Windows operating systems, environment variables can be set or unset from within the Project Navigator GUI.
From the Tcl Shell (available in 8.2i and later), type the following:
set env(<VARIABLE>) <value>
Example:
set env(TEMP) c:\temp
To remove or unset an environment variable from the Tcl shell, type:
unset env(<VARIABLE>)

puts $::env(<VARIABLE>)
