XISE_GHDL_SIMPRIM(1)         Retro Project Manual         XISE_GHDL_SIMPRIM(1)


NAME
       xise_ghdl_simprim - compile Xilinx ISE SIMPRIM libraries for GHDL

SYNOPSIS
       xise_ghdl_simprim [GHDL-OPTION]...

DESCRIPTION
       xise_ghdl_simprim compiles the Xilinx ISE/WebPack SIMPRIM libraries for
       ghdl.  The object files generated by ghdl are stored in  the  directory
       tree  of  the  currently  active  version  of  ISE/WebPack  under $XIL-
       INX/ghdl/simprim.

       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

       to link to the SIMPRIM library.

       Up to ISE 10 the VITAL models were all concatenated in one  large  file
       simprim_VITAL.vhd.   In  this  case, the xilinx_vhdl_chop helper script
       will create individual source files for each model.   For  ISE  11  and
       later the modules are shipped as separate files.

       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_simprim 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/WebPack installa-
              tion.

FILES
       $XTWI_PATH/ISE_DS/ISE/vhdl/src/simprims
              The  VHDL sources for the SIMPRIM library are looked for in this
              directory tree.

       $XTWI_PATH/ISE_DS/ISE/ghdl/simprim
              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.
