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:
vlog -work work F:/Modeltech_6.0/myexe/compare_test.v
Model Technology ModelSim SE vlog 6.0 Compiler 2004.08 Aug 19 2004
