We are providing for free and anyone can download, Graham's standard cells, alliance and many more design tools. Work has done to avoid those installation difficulties you have encountered. http://chitlesh.fedorapeople.org/FEL We are also working on providing these design tools for free again on the EPEL repository for the Entreprise class Linux distributions such as Centos and RHEL. https://fedoraproject.org/wiki/EPEL I would also invite you to have a look at "Toped VLSI Layout Editor". There are feedbacks from many users who deployed Toped for their companies. Kind regards, Chitlesh Goorah
