I have successfully downloaded Synopsys 28/32nm educational library, but I have not managed to make it work (in design compiler). [Where are the target library files ? I don't understand how it is organized ? It is a mess !]
So my question : is there good alternatives for free USABLE libraries out there ?
nangate freePDK is commonly used. please, do see my answer to your other topic. I believe you are not using the files the way they are meant to be used.

I think you misunderstood the concept of target libraries. They are nothing but the same library & will be used by the tool while performing synthesis.
Just go through what is link_library & target_library in DC user manual, I'm sure you will get it.
