ICC建立milkyway库出现警告，求助

Maeby

刚开始学习ICC，使用的是SMIC55nm库，在用create_mw_lib命令创建库时，出现下述警告：Warning: Layer 'M1' has rounded fat table thresholds '(0, 1, 5)'. (line 340) (TFCHK-055)
Warning: Layer 'RDL' is missing the attribute 'minArea'. (line 749) (TFCHK-012)
Warning: ContactCode 'VIA_RDV' is missing the attribute 'unitMinResistance'. (line 1295) (TFCHK-014)
Warning: ContactCode 'VIA_RDV' is missing the attribute 'unitNomResistance'. (line 1295) (TFCHK-014)
Warning: ContactCode 'VIA_RDV' is missing the attribute 'unitMaxResistance'. (line 1295) (TFCHK-014)

Warning: CapModel sections are missing. Capacitance models should be loaded with a TLU+ file later. (TFCHK-084)
想请教一下，1.这些警告影不影响后续库使用？2.这些警告为什么会出现，即为什么会出现这种不吻合现象？
