NAME

DPGEN_ROM4 - 4 words ROM Macro-Generator

SYNOPSIS

#include <genlib.h>

void GENLIB_MACRO (DPGEN_ROM4, char *modelname, long flags, long N, char *constVal0, char *constVal1, char *constVal2, char *constVal3);

DESCRIPTION

Generate a N bits 2 words optimized ROM named modelname.

TERMINAL NAMES

1.: sel1 : upper bit of the address (input, 1 bits).
2.: sel0 : lower bit of the address (input, 1 bits).
3.: q : the selected word (output, N bit).
4.: vdd : power.
5.: vss : ground.

BEHAVIOR

q <= WITH sel1 & sel0 SELECT contsVal0  WHEN B"00",


                             contsVal1  WHEN B"01",


                             contsVal2  WHEN B"10",


                             constVal3  WHEN B"11";
