lvs需要查看的是 open/short nets，input port不要有floating 请问除了这几个 其他的error 需要关心吗 ?
我route opt之后，verify_lvs出现：
(1) Total area error in layer 0 is 0.Elapsed =0:00:01, CPU =0:00:00
Total area error in layer 1 is 0.Elapsed =0:00:01, CPU =0:00:01
(2) ERROR : Short occur for different EEQ Class.
(3) ERROR : Pins of different Electrical Eqivalent class in PortInst oc8051_ram_top1_oc8051_ram1_u_ram_wrap_u_sram0 I1
[2](6771) Net TIEL_HVT！U191_net(130074) are connected

2) ,3) 都可以忽略吧
