XISE_GHDL_UNISIM(1)          Retro Project Manual          XISE_GHDL_UNISIM(1)


NAME
       xise_ghdl_unisim - compile Xilinx ISE UNISIM and UNIMACRO libraries for
       GHDL

SYNOPSIS
       xise_ghdl_unisim [GHDL-OPTION]...

DESCRIPTION
       xise_ghdl_unisim compiles the Xilinx ISE UNISIM and UNIMACRO  libraries
       for  ghdl.  The object files generated by ghdl are stored in the direc-
       tory  tree  of  the  currently  active  version  of  ISE  under   $XIL-
       INX/ghdl/unisim and $XILINX/ghdl/unimacro.

       Since  direct  calls  to  ISE  tools  are  in general encapsulated with
       xtwi(1) the $XTWI_PATH is used instead of $XILINX.  This  allows  using
       this script and ghdl without an xtwi wrapper.

       Just use the ghdl option

           -P${XWTI_PATH}/ISE_DE/ISE/ghdl/unisim
           -P${XWTI_PATH}/ISE_DE/ISE/ghdl/unimacro

       to link to the UNISIM or UNIMACRO library.

       The  Xilinx  source  code has since many releases some buggy statements
       with self-referential initializations. They seem to be tolerated by the
       commercial  tools  but  not  by  ghdl.  The xilinx_vhdl_memcolltype_fix
       helper script simply removes them, no further problems seen so far.

OPTIONS
       Options added after the xise_ghdl_unisim command are  simply  forwarded
       to  the  'ghdl  -a'  commands. In general, used to specify the optimize
       level.  If no options given -O2 -g is used.


ENVIRONMENT
       XTWI_PATH
              points to the root of the currently active ISE installation.

FILES
       $XTWI_PATH/ISE_DS/ISE/vhdl/src/unisims
              The VHDL sources for the Xilinx ISE UNISIM library

       $XTWI_PATH/ISE_DS/ISE/vhdl/src/unimacro
              The VHDL sources for the  Xilinx ISE UNIMACRO library

       $XTWI_PATH/ISE_DS/ISE/ghdl
              The created object files will be written  into  this  directory.
              The  directory  is  created if it does not exist yet.  Note that
              the $XTWI_PATH directory must be writable for the script.
