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 :

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

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

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

       · 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.

                             , 8   /* Number of words. */
                             );
