NAME
       xtwi - Xilinx Tool Wrapper script for ISE

SYNOPSIS
       xtwi [COMMAND]

DESCRIPTION
       The  Xilinx  ISE  setup script redefines PATH and LD_LIBRARY_PATH.  The
       ISE tools run fine in this environment, but other installed programs on
       the system can (and actually do) fail. xtwi helps to keep the ISE envi-
       ronment separate from the normal working environment.

       The environment variable XTWI_PATH must be set up to the  install  path
       of  the  ISE version to be used. Without the /ISE_DS/ which is added by
       the ISE installation procedure.

       xtwi uses XTWI_PATH to locate the ISE setup script, sources it, and ex-
       ecs  the  COMMAND. This way COMMAND is executed in the ISE environment,
       while the login shell stays clean.

       xtwi can also set up a clean environment when BARE_PATH and BARE_LD_LI-
       BRARY_PATH are defined.


ENVIRONMENT
       XTWI_PATH
           Install path of ISE, without the /ISE_DS/ appended by ISE installa-
           tion

       BARE_PATH
           Optional. If defined xtwi will set
              export PATH=$BARE_PATH:$RETROBASE/tools/bin
           LD_LIBRARY_PATH will be unset unless  BARE_LD_LIBRARY_PATH  is  de-
           fined too.

       BARE_LD_LIBRARY_PATH
           Optional. If defined xtwi will set
              export LD_LIBRARY_PATH=$BARE_LD_LIBRARY_PATH
           Used only when BARE_PATH is defined.

FILES
       $XTWI_PATH/ISE_DS/settings32.sh
       $XTWI_PATH/ISE_DS/settings64.sh
           ISE setup script located and sourced on 32 or 64 bit systems

NOTES
       If both ISE and Vivado are used xtwi and xtwv(1) offer a convenient way
       to have both tools available in one session without interference.

EXAMPLES
       xtwi netgen -sim  -intstyle xflow -ofmt vhdl -w test.ngc
           Starts the ISE netlister and generates a VHDL model from test.ngc.
