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 :

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
            );
