我新手,编了一个简单测试程序就是不能通过,好象是定义时间单位那里错误,程序是下面的:
'timescale 1us/1us
module compare(equ,a,b);
    input a,b;
    output equ;
    assign equ=(a==b)?1:0;
endmodule
module tc; 
    reg a,b;
    wire equ;
    initial
    begin
        a=0;
        b=0;
        #100 a=0;b=1;
        #100 a=1;b=1;
        #100 a=1;b=0;
        #100 a=0;b=0;
        #100 $stop;
    end  
    compare m(.equ(equ),.a(a),.b(b));
endmodule
出现下面错误提示:

这是什么原因啊,求助/
