NAME
       DPGEN_FIFO - FIFO Macro-Generator

SYNOPSIS
       #include  <genlib.h>

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

DESCRIPTION
       Generate a FIFO of regNumber words of N bits named modelname.

       How it works :

       o datain0 and datain1 : the two write busses. Only one is used to actually write the FIFO, it is selected by the sel signal.

       o sel : when set to '0' the datain0 is used to write the register word, otherwise it will be datain1.

       o r, rok : set r when a word is requested, rok tells that a word has effectively been popped (rok == not empty).

       o w, wok : set w when a word is pushed, wok tells that the word has effectively been pushed (wok == not full).

   TERMINAL NAMES
       1. ck : clock signal (input, 1 bit).

       2. reset : reset signal (input, 1 bit).

       3. r : read requested (input, 1 bits).

       4. w : write requested (input, 1 bits).

       5. rok : read acknowledge (output, 1 bits).

       6. wok : write acknowledge (output, 1 bits).

       7. sel : select the write bus (input, 1 bit).

       8. datain0 :  first write bus (input, N bits).

       9. datain1 :  second write bus (input, N bits).

       10.
	  dataout : read bus (output, N bits).

       11.
	  vdd : power.

       12.
	  vss : ground.

EXAMPLE
       GENLIB_MACRO(DPGEN_RF1, "model_fifox8_32"

			     , 32  /* Words size.      */
			     , 8   /* Number of words. */
			     );
