modelsim的使用，MIF文件调用，正弦波生成

程序调用MIF文件前是这样的
`timescale 1ns/1ns

`define clk_period 20

module sin_bb;
reg[5:0]addr;
reg clk;

wire[7:0]q;


  sin sin (
        .address(addr),
        .clock(clk),
        .q(q));

   initial clk=1;
        always #(`clk_period/2) clk=~clk;
        integer i;
       
        initial begin
           addr=0;
                for(i=0;i<63;i=i+1)begin
                #`clk_period;
                addr=addr+1;
                end
                #(`clk_period* 50);
                $stop;
        end
endmodule



程序在调用mif文件后是这样的
LIBRARY ieee;
USE ieee.std_logic_1164.all;

LIBRARY altera_mf;
USE altera_mf.all;

ENTITY sin IS
        PORT
        (
                address                : IN STD_LOGIC_VECTOR (5 DOWNTO 0);
                clock                : IN STD_LOGIC  := '1';
                q                : OUT STD_LOGIC_VECTOR (7 DOWNTO 0)
        );
END sin;


ARCHITECTURE SYN OF sin IS

        SIGNAL sub_wire0        : STD_LOGIC_VECTOR (7 DOWNTO 0);
