My company, Semantic Designs, has a Reengineering Toolkit and a related
tool, CloneDR, that might help. CloneDR ("clone doctor") detects exact and
near-miss blocks of identical code fragments (without being told what to
look for) in large-scale sources (on up to 1 million lines of source code.)
We've used the CloneDR on a VHDL DLX design. Among "duplicate" fragments,
it found, it discovered that instruction and data caches were parameterized
by bus and clock signals. CloneDR could be used for counting modules;
quality analysis; and possibly IP extraction. See http://www.semdesigns.com
