  • Patent number: 6842884
    Abstract: An equivalence checking method provides first and second logic functions. Don't care gates are inserted for don't care conditions in the first and second logic functions. The insertion of the don't care gates creates a first intermediate circuit and a second intermediate circuit. All 3DC gates of the first intermediate circuit are propagated and merged into a single 3DC gate when 3DC gates and SDC gates coexist in either of the first and second intermediate circuits. All 3DC gates of the second intermediate circuit are propagated and merged into a single 3DC gate when 3DC gates and SDC gates coexist in either of the first and second intermediate circuits. First and second circuits are produced in response to propagating and merging the 3DC gates. A combinational equivalence check is then performed of the first circuit to the second circuit under different equivalence relations.

  • Patent number: 6801949
    Abstract: A scalable, distributed, highly available, load balancing server system having multiple machines is provided that functions as a front server layer between a network (such as the Internet) and a back-end server layer having multiple machines functioning as Web file servers, FTP servers, or other application servers. The front layer machines comprise a server cluster that performs fail-over and dynamic load balancing for both server layers. The operation of the servers on both layers is monitored, and when a server failure at either layer is detected, the system automatically shifts network traffic from the failed machine to one or more operational machines, reconfiguring front-layer servers as needed without interrupting operation of the server system. The server system automatically accommodates additional machines in the server cluster, without service interruption. The system operates with a dynamic reconfiguration protocol that permits reassignment of network addresses to the front layer machines.
