Hello which path can i find the "nfet_01v8.lib" file on?

@Zineddine Haboussi I may be mistaken, but I think

.lib

files are might be used for timing/power estimates at the gate level (verilog). I don’t know that there is timing/power information at the discrete device level. Do you mean the spice models for

nfet_01v8

? If so, you can find them here

$PDK_ROOT/$PDK/libs.ref/sky130_fd_pr/spice

.
