隊列的一個簡單使用是通過自帶的方法實現(xiàn)FIFO（先進先出）

push_back()
pop_front()

代碼：

string fruits[$] = {"orange","apple","kiwi"}; initial begin foreach(fruits[i])$display("fruits[%0d] = %s",i, fruits[i]);$display("fruits = %p", fruits);fruits.push_back("aaa");$display("fruits = %p",fruits);fruits.pop_front();$display("fruits = %p",fruits);fruits = {};$display("After deletion,fruits = %p",fruits); end

結(jié)果：

# fruits[0] = orange # fruits[1] = apple # fruits[2] = kiwi # fruits = '{"orange", "apple", "kiwi"} # fruits = '{"orange", "apple", "kiwi", "aaa"} # fruits = '{"apple", "kiwi", "aaa"} # After deletion,fruits = '{}

總結(jié)
