Patent number: 9330222Abstract: Disclosed are methods, systems, and articles of manufacture for implementing electronic circuit designs with electro-migration awareness. Some embodiments perform schematic level simulation(s) to determine electrical characteristics, identifies physical parasitics of a layout component, determines the electrical or physical characteristics associated to electro-migration analysis on the component, and determines whether the component meets EM related constraint(s) while implementing the physical design of the electronic circuit in some embodiments. Some embodiments further determine adjustment(s) to the component or related data where the EM related constraints are not met and/or and present the adjustment(s) in the form of hints. Various data and information, such as currents in various forms or voltages, are passed between various schematic level tools and physical level tools.Type: GrantFiled: December 30, 2010Date of Patent: May 3, 2016Assignee: Cadence Design Systems, Inc.Inventors: David White, Michael McSherry, Ed Fischer, Bruce Yanagida, Prakash Gopalakrishnan

Patent number: 9223925Abstract: Disclosed are methods, systems, and articles of manufacture for implementing electronic designs with simulation awareness. A schematic is identified or created and simulated at the schematic level to characterize the functional behavior of the circuit or to ensure the circuit design meets the required design specifications. Physical data of a component of the design is identified, created, or updated, and the electrical parasitic associated with physical data is characterized. One or more electrical characteristics associated with the parasitic is further characterized and mapped to the simulator to re-simulate the circuit design to analyze the impact of parasitics. Some embodiments re-run the same simulation process incrementally in an interactive manner by accepting incremental design or parameter changes from the design environment.Type: GrantFiled: April 7, 2014Date of Patent: December 29, 2015Assignee: Cadence Design Systems, Inc.Inventors: Prakash Krishnan, Michael McSherry, David White, Ed Fischer, Bruce Yanagida, Keith Dennison

Patent number: 8762914Abstract: Disclosed are methods, systems, and articles of manufacture for constraint verification for implementing electronic circuit designs with electrical awareness. Some embodiments identify or set parasitic constraint(s) and compare the electrical parasitic(s) with corresponding parasitic constraint(s) to determine whether the parasitic constraints are met. Some embodiments first identify, determine, or update the physical data of a component of a partial layout and characterize the electrical parasitics associated with the physical data of the component. Some embodiments identify or determine some schematic level performance constraints and estimate parasitic constraints based on schematic simulation results and the performance constraints; the estimated parasitic constraints are then compared with the corresponding electrical parasitics to determine whether the constraints are satisfied.Type: GrantFiled: December 30, 2010Date of Patent: June 24, 2014Assignee: Cadence Design Systems, Inc.Inventors: Ed Fischer, Michael McSherry, David White, Bruce Yanagida, Akshat Shah

Patent number: 8694950Abstract: Disclosed are a method, system, and computer program product for implementing electronic circuit designs with electrical awareness. The method or the system updates the schematic level tool(s) and physical design tool(s) with electrical parasitic data or electrical characteristic data associated with electrical parasitics so both schematic and physical design tools are aware of the electrical parasitic or characteristic data in performing their functions such as extraction based simulations. The methods or systems are also aware of EM or IR-drop constraint(s) while implementing or creating a partial layout less than a complete layout. The method or the system also provides a user interface for a design tool to provide in situ, customizable, real-time information for implementing electronic circuit designs with electrical awareness. The methods or systems also support constraint verification for electronic circuit design implementation with electrical awareness.Type: GrantFiled: December 30, 2010Date of Patent: April 8, 2014Assignee: Cadence Design Systems, Inc.Inventors: Michael McSherry, David White, Ed Fischer, Bruce Yanagida, Prakash Gopalakrishnan, Keith Dennison, Akshat Shah

Patent number: 6354259Abstract: A method for the manufacture of a cylinder liner for combustion engines and a cylinder liner which can be manufactured by the method according to the invention are disclosed. The method comprises a thermal spray-deposition, such as by an arc spray-deposition process, of a wearing layer on a supporting body and a spray-deposition of a protective or connecting layer on the wearing layer. The wearing layer comprises a hypereutectic aluminum-silicon alloy and the protective or connecting layer comprises a hypoeutectic aluminum-silicon alloy. A melt retarder of iron, for example, may be interposed between these two layers. The melt retarder comprises a higher melting temperature than the two aluminum-silicon alloys, thereby preventing the wearing layer from partially melting when the cylinder liner is cast into a cylinder bore.Type: GrantFiled: April 10, 2001Date of Patent: March 12, 2002Assignee: Federal-Mogul Friedberg GmbHInventors: Manfŕed Fischer, Rudólf Mundl, Peter Gödel, Wolfgang Reichle, Werner Trübenbach, Markus Müller, Reinhard Rosert
