Unfortunately SCR is a very old tool, main authors have left our laboratory and there is no such features. A member of our team (Christophe Alexandre) is working on a new Place and Route Tool. It will may be part of a new Alliance release. But as far as i know there is no such complex options in this new tool too. > > 5. How can we perform Compaction using the tool ? > > 6. What is the maximum limit of metal layers in Alliance ? It depends of the Alliance version you use. SCR works only with 2 metal layers, but our internal data structure can use up to 9 Metal layers. > > Kindly help us to sort out the above problems. > Waiting for your reply. > > regards, > > Shiv N.
