Hello guys, i have two file "lef" and "def", how can i visualize them in magic?
I tried both command, "lef ready &lt;file&gt;" and "def ready &lt;file&gt;", but i get this error...

If you are reading a DEF file or a LEF macro library, you may need to read a LEF technology file first.  But this is usually defined in the tech file for magic.  What technology are you running in magic, and what technology is defined by the LEF/DEF files?

It Is refered to Sky130, the .tech file Is correctly defined.

Names "v1" and "v2" are not used by any LEF files in the PDK.  And the cut sizes in the LEF file are the wrong size;  in fact _all_ of the cut sizes look wrong.

On the other hand, none of this may actually matter in viewing the LEF (or DEF) file.  For the LEF file, though, you probably want to follow up with a `load` command.   A LEF macro library does not define a top-level cell;  do `cellname top` to list the cells after reading LEF, or use the cell manager window.
