Hi, I am using Space Based Custom digital placer of virtuoso. Before the power ring generation and vias placement we need to load this skill file. Where to find this file? I have one but I think it is not working as I am still seeing the global nets of standard cells. While importing the synthesized gate level netlist, I gave in global power option: vdd and gnd. But in the rows and power rings I am still seing vdd! and gnd!. Another problem is that I am unable to place vias. It is showing that command is running but saying that 0 connection made. Please help
