How to include certain cells in synopsys design compiler

[Holzapfel]

Hi everyone,

In synopsys design compiler, I only want to use several cells during optimization. I know "set_dont_use", but this command is too long and complex since I only want to use 10 cells... Is there any opposite command of "set_dont_use" something like "set_only_use" in synopsys design compiler?

Many thanks!

set_dont_use [get_lib_cell *] true
set_dont_use [get_lib_cell a b c] false

set_dont_use [get_lib_cell *] true
set_dont_use [get_lib_cell a b c] false

Hi, many thanks!

For me somehow I cant set true or false, I use "set_dont_use" and "remove_attribute dont_use" instead
