下面程序：
module blocking_nonblocking();
reg a,b,c,d;
// Blocking Assignment
initial begin
#10 a = 0;
#11 a = 1;
#12 a = 0;
#13 a = 1;
end
initial begin
#10 b <= 0;
#11 b <= 1;
#12 b <= 0;
#13 b <= 1;
end
initial begin
c = #10 0;
c = #11 1;
c = #12 0;
c = #13 1;
end
initial begin
d <= #10 0;
d <= #11 1;
d <= #12 0;
d <= #13 1;
end
initial begin
$monitor("TIME = %g A = %b B = %b C = %b D = %",$time, a, b, c, d);
#50 $finish;
end
endmodule
怎样操作得到如下输出：
TIME = 0 A = x B = x C = x D = x TIME = 10 A = 0 B = 0 C = 0 D = 0 TIME = 11 A = 0 B = 0 C = 0 D = 1 TIME = 12 A = 0 B = 0 C = 0 D = 0 TIME = 13 A = 0 B = 0 C = 0 D = 1 TIME = 21 A = 1 B = 1 C = 1 D = 1 TIME = 33 A = 0 B = 0 C = 0 D = 1 TIME = 46 A = 1 B = 1 C = 1 D = 1
module blocking_nonblocking();
reg a,b,c,d;
// Blocking Assignment
initial begin
#10 a = 0;
#11 a = 1;
#12 a = 0;
#13 a = 1;
end
initial begin
#10 b <= 0;
#11 b <= 1;
#12 b <= 0;
#13 b <= 1;
end
initial begin
c = #10 0;
c = #11 1;
c = #12 0;
c = #13 1;
end
initial begin
d <= #10 0;
d <= #11 1;
d <= #12 0;
d <= #13 1;
end
initial begin
$monitor("TIME = %g A = %b B = %b C = %b D = %",$time, a, b, c, d);
#50 $finish;
end
endmodule
