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 :

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
            );
