注意: repeat不能单独成块一定要在initial 或always中,谢谢【炼灵】iceshy!

module Func_tb;

// Inputs
reg clk;
reg rst;
reg [2:0] n;
reg [1:0] sl;

// Outputs
wire [6:0] result;

// Instantiate the Unit Under Test (UUT)
Func uut (
.clk(clk),
.rst(rst),
.n(n),
.sl(sl),
.result(result)
);

initial begin
// Initialize Inputs
clk = 0;
rst = 0;
n = 0;
sl = 0;

//100ns 后初始化
#100;
rst = 1;
clk = 1;
end

   always #10 clk = ~clk;
   repeat(50)
   begin
#10 n = {$random} % 6;
sl = {$random} % 3;
end

endmodule

错误：
ERROR:HDLCompiler:806 - "D:/Xilinx_prj/Demo_v/Func/Func/Func_tb.v" Line 59: Syntax error near "repeat".
ERROR:HDLCompiler:598 - "D:/Xilinx_prj/Demo_v/Func/Func/Func_tb.v" Line 25: Module <Func_tb> ignored due to previous errors.
