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 :

       • datain0 and datain1 : the two write busses. Only one  is  used  to  actually  write  the
         register word, 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.

       • 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
                   );
