Hi, Does anyone know How can I simulate the .spice that openlane gives me at the end of the layout, because it imported the file but it doesn't recognize it and I don't know if it's because there are many internal blocks?

@Juan Andres I’ve never run spice myself, but looks like this is the extracted lef version. You might be able to delete all the empty subcircuit definitions and

.include $PDK_ROOT/$PDK/libs.ref/sky130_fd_sc_hd/spice/sky130_fd_sc_hd.spice

. You want to make sure are the terminals are extracted in the same order as the library though.

however, it doesn't work
