后置位置和路径模拟时间违规

我在行为模拟方面获得了完美的结果,但是当简单地运行后置位置和路径模拟时
以下警告即将来临。
我没有给出任何时序限制,我只是简单地运行后置和路由模拟。
请帮帮我。

i am getting perfect results in behavioural simulation , but when simply run post-place and route simulation then

the following warnings are coming. I am not giving any timing constraints , I am simply running post-place and route simulation. PLEASE HELP ME.
