41 Reaching Our Main Goal  I/O Count > 200  Serialization  Increased Power  This led to…

42 Conclusion  Gripe is always up to increase your quota  Changing schematics while someone is trying to LVS the top-level layout leads to tears  We are proud of our design (no pre- discovered algorithms used)
