请教一个错误：刚接触modelsim不熟悉，实在是弄不了。谢谢赐教。
编译完，启动仿真后就出现这种错误。

没有源代码，不好定位，你最好找个装有quartus的人帮你试一下。我用的是ISE
Modelsim已经指出你bench文件vga_testbench.vhd在实例化顶层vga_controller_stream时出现错误(line40)，先检查testbench代码有没有错误吧。
谢谢。我试试，这个论坛好，人气
元件声明：
component vga_controller_stream is
port(
address:IN std_logic;
clk :IN std_logic;
reset :IN std_logic;
chipselect: IN std_logic;
enwrite: IN std_logic;
writedata:in std_logic_vector(7 downto 0);
readyfordata: out std_logic;
endofpacket ut std_logic;
hsync: out std_logic;
vsync: out std_logic;
rgb: out std_logic_vector(7 downto 0)
);
错误行：
DUT : vga_controller_stream PORT MAP(address => address, clk => clk, reset => reset,chipselect => chipselect,enwrite => enwrite,writedata => writedata,readyfordata => readyfordata,endofpacket => endofpacket,hsync => hsync,vsync => vsync, rgb => rgb);
顶层文件为verilog的：
接口说明为：
module vga_controller_stream(
clk,reset,chipselect,enwrite,writedata,readyfordata,endofpacket,address,hsync,vsync,rgb);
input address;
input clk;
input reset;
input chipselect;
input enwrite;
input[7:0] writedata;
output readyfordata;
output endofpacket;
output hsync;
output vsync;
output[7:0] rgb;
没有问题吧！?
我ms也遇到过相同的问题
你怎么解决的呢?
检查一下格式是否有问题，如果你的帖子是直接copy你的代码，看看这里：
endofpacket: out std_logic;
这里没有错误。
有没有Verilog和VHDL混用啊！
TB错误
你好，我也遇到同样的问题了 你是怎么解决的啊?能不能分享下
