DPGEN_RF1(3)		Alliance - genlib User's Manual		  DPGEN_RF1(3)

NAME
       DPGEN_RF1, DPGEN_RF1R0 -	Register File Macro-Generator

SYNOPSIS
       #include	 <genlib.h>

       void GENLIB_MACRO (DPGEN_RF1, char *modelname, long flags, long N);

       void GENLIB_MACRO (DPGEN_RF1R0, char *modelname,	long flags, long N);

DESCRIPTION
       Generate	 a  register file of regNumber words of	N bits whitout decoder
       named modelname.	The DPGEN_RF1R0	variant	differs	from the DPGEN_RF1  in
       that  the register of address zero is stuck to zero. You	can write into
       it, it will not change the value. When  read,  it  will	always	return
       zero.

       How it works :

       o datain0 and datain1 : the two write busses. Only one is used to actu-
	 ally write the	register word, 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 selr,	selw  :	this register file have	no decoder, so selr have a bus
	 width equal to	regNumber. One bit for each word.

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

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

       3. selr : the decoded read address (input, regNumber bits).

       4. selw : the decoded write address (input, regNumber bits).

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

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

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

       8. vdd :	power.

       9. vss :	ground.

EXAMPLE
       GENLIB_MACRO(DPGEN_RF1, "model_rf1x8_32"
			     , F_BEHAV|F_PLACE
			     , 32  /* Words size.      */
			     , 8   /* Number of	words. */
			     );

       GENLIB_LOINS( "model_rf1x8_32"
		   , "instance1_rf1_32"
		   , "ckok"
		   , "sel"
		   , "selr[7:0]"
		   , "selw[7:0]"
		   , "datain0[31:0]"
		   , "datain1[31:0]"
		   , "dataout[31:0]"
		   , "vdd", "vss", NULL
		   );
