how to view layout in cadence virtuoso with lef?

I have LEF, DEF, LIB, PLIB, DB, etc. all files from SoC and such but no gds. These files are from ARM with general I/O and pad cell but I need to see them with virtuoso. One person told me maybe a synopsys function called fdi2gds on the lef file, but I'm not sure how to use it.
