Hi, people. thanks for being here to help. I am porting a design from 180nm to 130nm pdk. The nfet size used in OSU 180nm design is 0.18/0.18. However, this sizing is not available in sky130nm (sky130_fd_pr). I need to get the sizing right for the ckt to work. What equivalent sizing of nfet should I use in sky130nm pdk ? the nearest size in sky130nm is 1/1 or 0.36/0.18 , neither gives optimal results.
