Patent number: 8418093Abstract: Methods and systems are provided for reducing an original circuit design into a simplified circuit design by merging gates that may not be equivalent but can be demonstrated to preserve target assertability with respect to the original circuitry design. A composite netlist is created from the simplified netlist and the original netlist. The composite netlist includes a number of targets that imply the existence of a target in the simplified netlist and a corresponding target in the original netlist. The implications are verified and then validated to ensure the simplified circuit design is a suitable replacement for the original circuit design.Type: GrantFiled: May 15, 2009Date of Patent: April 9, 2013Assignee: International Business Machines CorporationInventors: Jason R.

Patent number: 8201117Abstract: A method, system and computer program product for integrating implication-based analysis and equivalent gate analysis to maintain transitive reduction in an implication graph over a sequence of graph operations. One or more gates of a design are identified that are equivalent in all reachable states. Equivalent gates are assigned to an equivalence class when all gates within the equivalence class are equal. During the implication-based analysis the system determines when one or more implication paths are associated with the one or more equivalence classes, and an implication is generated at the implication path associated with the equivalence classes. A transitively reduced graph is received depicting the implications and equivalence classes of the design. When one or more operations are assigned to the transitively reduced graph, the graph is automatically adjusted to maintain transitive reduction.Type: GrantFiled: January 22, 2009Date of Patent: June 12, 2012Assignee: International Business Machines CorporationInventors: Jason R.

Patent number: 8171437Abstract: A method, system and computer program product for X-Saturated ternary simulation based reduction. An X-Saturated ternary simulation (XSTS) utility, which executes on a computer system, receives design information, where the design information includes a netlist. The XSTS utility initializes one or more data structures and/or variables and simulates, in a ternary fashion, the netlist at a time value by applying logical X values to all RANDOM gates of the netlist and to registers marked X_SATURATED. For each register of the netlist XSTS utility: determines whether or not the register departs from its expected prefix behavior, and if the register departs from its expected prefix behavior, the register is marked as X_SATURATED and the current state is updated with an X value upon the register. XSTS utility can store the current state in a data structure and can use the information from the data structure to simplify the design.Type: GrantFiled: March 25, 2009Date of Patent: May 1, 2012Assignee: International Business Machines CorporationInventors: Jason R. Baumgartner, Michael L. Case, Geert Janssen, Hari Mony
