The Linux version depends on the downloaded version of the software. Old software needs old Linux OS. Newer software needs newer Linux OS. I have successfully installed on Redhat and SuSE in my company. Other people has installed on Ubontu and CentOS. But I think Redhat and SuSE give me less head ache.
I've install the 2015 Synopsys Tools on RHEL 7.1, they work fine, but there's some minor issue about the lmgrd, so, I guess RHEL6.x or Cent6.x is still the best choice, even for tool of 2015
