NAME
       DPGEN_NOR2MASK - Programmable Mask Macro-Generator

SYNOPSIS
       #include  <genlib.h>

       void GENLIB_MACRO (DPGEN_NOR2MASK, char *modelname, long flags, long N, char *constVal);

DESCRIPTION
       Generate a N bits conditionnal NOR mask named modelname.

       How it works :

       o if the cmd signal is set to '0', the mask is NOT applied, so the whole operator behave like an inverter.

       o if  the  cmd  signal  is  set	to  '1',  the mask IS applied, the output is the complemented result of the input value ORed with the mask
	 (suplied by constVal).

       The constant constVal is given to the macro-generator call, therefore the value cannot be changed afterward : it's hard wired in the opera-
       tor.

       A common error is to give a real C constant for the constVal argument. Be aware that it is a character string.

   TERMINAL NAMES
       1. cmd : mask control (1 bit).

       2. i0 : input (N bits).

       3. q : output (N bits).

       4. vdd : power.

       5. vss : ground.

   BEHAVIOR
       nq <= WITH cmd SELECT not(i0)		    WHEN '0',
			     not(i0 or X"0000FFFF") WHEN '1';

EXAMPLE
       GENLIB_MACRO(DPGEN_NOR2MASK, "model_nor2mask_0000FFFF_32"
				  , F_BEHAV|F_PLACE
				  , 32
				  , "0x0000FFFF" /* A string! */
				  );

       GENLIB_LOINS( "model_nor2mask_0000FFFF_32"
		   , "instance1_nor2mask_32"
		   , "cmd"
		   , "i0[31:0]"
		   ,  "q[31:0]"
		   , "vdd", "vss", NULL
		   );
