Quartus II 调用Modelsim仿真实例--出错，请教！
《Quartus II 调用Modelsim仿真实例》编写 modelsim_test.v 文件 Quartus II 编译通过
编写 tb_test.v 文件
打开Modelsim ，New --Library；
Compile 工程文件夹下 3个文件，
tb_test.v
maxii_atoms.v
modelsim_test.vo通过
然后 双击 vtf_test
即Simulation，出错，出错信息如下
# vsim work_test.vtf_test

说 sdf file not found
请问 这个问题如何解？
软件版本 QuartusII 8.1 Modelsim SE PLUS 6.2b
PS:
//**************以下为modelsim_test.v文件*******************
module modelsim_test(clk,rst_n,div);
input clk;
input rst_n;
output div;
reg div;
always@(posedge clk or negedge rst_n)
if(!rst_n) div<=1'b0;
else div<=~div;
endmodule
//**************以下为tb_test.v 文件*******************
module vtf_test;
reg clk;
reg rst_n;
wire div;
modelsim_test u1(.clk(clk),.rst_n(rst_n),.div(div));
initial begin
clk=0;
forever
#10 clk=~clk;
end
initial begin
rst_n=0;
#1000 rst_n=1;
#1000;
$stop;
end
endmodule 回复【楼主位】ling010512
