how to get a collection of all lib_cells used in design?

[xchuang]

my design is a hierarchy design included many ips , how to get a collection of all lib_cells used in design?

 

[itsmeteja]

first run the link or link -force

Analyze for linking errors.If you do not have any, then report list_libs command get all the libs loaded in the design.

Or
set ofile [open refs.txt w]
foreach_in_collection cell [get_cells -all] {
set ref [get_attr $cell ref_name]
puts $ofile $ref
}
close $ofile

exec sort -u refs.txt > ref.txt
exec mv ref.txt refs.txt
