5、t 短路时，或者不同的 label 标记到了同一 net 上时，出现这种 warning，lvs 中会忽略掉其中一个 label，将这个 net 定义为另一个 label 的名字，例如这个例子中这个 net 被定义为”osc32k”，忽略掉了”tclk_control”。这两个 warning 一般会同时出现解决办法是通过坐标和labellayout中查找short方，或者是label移位的地方。这个warning会引起layoutnetli stnet，一定要改掉；file file ing 是由于在 netlist 中重复定义了”NAND4”和”NOR2”这两个标准单元引起，可以修改 ne
