DPGEN_ADSB2F(3)		Alliance - genlib User's Manual	       DPGEN_ADSB2F(3)

NAME
       DPGEN_ADSB2F - Adder/Substractor	Macro-Generator

SYNOPSIS
       #include	 <genlib.h>

       void GENLIB_MACRO (DPGEN_ADSB2F,	char *modelname, long flags, long N);

DESCRIPTION
       Generate	a N bits adder/substractor named modelname.

       How it works :

       o if  the add_sub signal	is set to '0' an addition is performed,	other-
	 wise it's a substraction.

       o Operation can be either signed	or unsigned. In	unsigned mode  c31  is
	 the overflow, in unsigned mode	you have to compute overflow by	XORing
	 c31 and c30.

   TERMINAL NAMES
       1. add_sub : select addition or substraction (input, 1 bit).

       2. c31 :	carry out. In unsigned mode, this is the overflow  (output,  1
	  bits).

       3. c30  : used to compute overflow in signed mode : overflow := c31 xor
	  c30 (output, 1 bits).

       4. i1 : first operand (input, N bits).

       5. i0 : second operand (input, N	bits).

       6. q : output (N	bits).

       7. vdd :	power.

       8. vss :	ground.

EXAMPLE
       GENLIB_MACRO(DPGEN_ADSB2F, "model_adsb2f_32"
				   , F_BEHAV|F_PLACE
				   , 32
				   );

       GENLIB_LOINS( "model_adsb2f_32"
		   , "instance1_adsb2f_32"
		   , "add_sub"
		   , "c32"
		   , "c31"
		   , "i1[31:0]"
		   , "i0[31:0]"
		   ,  "q[31:0]"
		   , "vdd", "vss", NULL
		   );
