Question

module stimulus;
reg [511:0]FROM_LS;
reg CLOCK;
reg [2:0]HMIC_CTRL;
reg [20:0]BRANCH_CTRL;
reg  [63:0]TO_IF_ID;
reg FLUSH_CTRL;
reg [20:0]TO_LS;

inst_line_buf ILB(FLUSH_CTRL,TO_LS,FROM_LS,CLOCK,HMIC_CTRL,BRANCH_CTRL,TO_IF_ID);

// setup clock
initial
 begin

  #10 CLOCK = ~CLOCK;

// apply stimulus

  FROM_LS[511:480]= 32'b00011_00000_00100_01100_11100_10111_01;
  FROM_LS[479:448]=32'b000_11000_00100_01111_11111_00011_1000;

  HMIC_CTRL[2:0]=3'b000;
  BRANCH_CTRL[20:0]=20'b00000_00000_00000_00000;
  #2 $display("FLUSH CONTROL=%b, TO_LS= %b",FLUSH_CTRL,TO_LS);
end

endmodule

我收到以下错误：

除非您向我们展示完整的错误消息，以及您的vsim命令行和一些相关的Verilog代码，否则我们可以向您提供您的错误消息建议。

例如，来自modelsim_FAQ：

ModelSim模拟选项没有已正确设置（项目设置＆gt; ModelSim＆gt;选项）进行以下操作更改：右键单击Simulation “项目流”窗口中的选项卡或选择项目＆gt;设置＆gt;模拟 Testbench模块名称：指定您的 testbench模块名称顶级测试平台中的实例名称： DUT的实例名称请参阅以下是一个例子的截图。

更新：现在您已添加了一些代码，ILB看起来很可疑。您首先将它用作inst_line_buf模块的实例名称，然后在initial块中再次使用它作为函数或任务调用。我的猜测是你希望它在initial块之外，但是有端口连接：

inst_line_buf ILB (FROM_LS,CLOCK,HMIC_CTRL,TO_IF_ID,FLUSH_CTRL,TO_LS);
