Hi all, After doing sroute for pad pins only, the connectivity report gives the following violations: Net VCC, Pin VDD_PAD.VCC: unconnected terminal at (696.070000,1633.320000) (732.870000,1636.800000) Net VCC: special open at (265.350000,265.350000) (1371.450000,1423.350000) Net GND, Pin VSS_PAD.GND: unconnected terminal at (696.070000,0.000000) (732.870000,3.480000) Net GND: special open at (273.960000,213.250000) (1362.840000,1361.240000) Where: VDD_PAD: is the VDD pad, and the pin VCC is the only pin defined for it in the lef. The same for VSS_PAD. My lef power, ground pins either for standard cells or core power pads is VCC, and GND, and also I defined my global nets in encounter to be the same names. I used those commands for global connect: globalNetConnect VCC -type pgpin -pin VCC -inst * globalNetConnect VCC -type net -net VCC globalNetConnect VCC -type tiehi globalNetConnect GND -type pgpin -pin GND -inst * globalNetConnect GND -type net -net GND globalNetConnect GND -type tielo My thoughts tell me that I can ignore the unconnected terminals warnings, because it will be connected using i/o filler cells to complete the power ring for pads. Attached is a pic. for my chip with violation markers. Any help how can I solve this ! Thanks you. AbdUllah,
