就是一个很普通的4位计数器，不知道是什么错误，脑浆都要爆出来了
经常会出现这个错误提示：
A begin/end block was found with an empty body.
module counter_4(Q, clk, clr);
input clk, clr;
output Q;
reg [3:0] Q;
always @(posedge clk)
begin
if(clr)
Q <= 4'b0;
else
Q <= Q + 1;
end
endmodule
`define FALSE 1'b0;
`define TRUE 1'b1;
module counter_4_tb;
wire [3:0] count;
reg CLOCK, CLEAR;
counter_4 counter(count, CLOCK, CLEAR);
initial
$monitor($time, "count = %b", count);
// set CLOCK
initial
begin
CLOCK = `TRUE;
forever #5 CLOCK = ~CLOCK;
end
// set CLEAR
initial
begin
CLEAR = `TRUE;
repeat (5) @(negedge CLOCK);
CLEAR = `FALSE;
end
endmodule
