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, otherwise 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"

		   , "i1[31:0]"

NAME

       DPGEN_DFFT - Dynamic Flip-Flop with Scan-Path Macro-Generator

SYNOPSIS

       #include  <genlib.h>

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

DESCRIPTION

       Generate  a N bits dynamic flip-flop with scan-path named modelname. The two latches of this flip-flop are dynamic, i.e. the data is stored
       in a capacitor.

       How it works :

       o scan when set to '1' enables the scan-path mode.  Note that in scan-path mode, the wen signal is not effective.

       o scin : the input of the scan-path. This terminal is different from i0[0].

	 The scout is q[N-1] (in the following example this is q[31]).

       o wen when set to '1' enables the writing of the flip-flop.

   TERMINAL NAMES
       1. scan : scan-path mode (input, 1 bit).

       2. scin : scan path in (input, 1 bit).

       3. wen : write enable (input, 1 bit).

       4. ck : clock signal (input, 1 bit).

       5. i0 : data input (N bits).

       6. q : output (N bits).

       7. vdd : power.

       8. vss : ground.

EXAMPLE

       GENLIB_MACRO(DPGEN_DFFT, "model_dfft_32"
			      , F_BEHAV|F_PLACE
			      , 32
			      );

       GENLIB_LOINS( "model_dfft_32"
		   , "instance1_dfft_32"
		   , "scan"
		   , "scin"
		   , "wen"
		   , "ck"
		   , "i0[31:0]"
		   ,  "q[31:0]"  /* a[31] is "scout". */
		   , "vdd", "vss", NULL
		   );
