Patent number: 8081010Abstract: Self Restoring Logic (SRL) provides for SEU tolerance in high speed circuits. An SRL cell is designed to be stable in one of two internal states. Upon an SEU event, the SRL cell will not transition between the internal stable states and recover from an SEU. SRL circuits are realized with SRL storage cells driving succeeding SRL storage cells directly or through combinational logic such that the corruption of any one internal state variable in the driving SRL cell and it's the associated combinational output logic can affect at most one internal state variable of the succeeding SRL cell. An SRL circuit does not allow propagation of single SEU faults.Type: GrantFiled: November 24, 2010Date of Patent: December 20, 2011Assignee: ICS, LLCInventors: Sterling R. Whitaker, Gary K. Maki, Lowell H. Miles

Patent number: 7624368Abstract: An application specific integrated circuit is optimized by translating a first representation of its digital design to a second representation. The second representation includes multiple syntactic expressions that admit a representation of a higher-order function of base Boolean values. The syntactic expressions are manipulated to form a third representation of the digital design.Type: GrantFiled: November 4, 2005Date of Patent: November 24, 2009Assignee: STC.UNMInventors: Sterling R. Whitaker, Lowell H. Miles

Patent number: 6792589Abstract: A digital integrated circuit chip is designed by identifying a logical structure to be implemented. This logical structure is represented in terms of a logical operations, at least 5% of which include selection operations. A determination is made of logic cells that correspond to an implementation of these logical operations.Type: GrantFiled: June 14, 2002Date of Patent: September 14, 2004Assignee: Science & Technology Corporation @ UNMInventors: Sterling R. Whitaker, Lowell H. Miles, Eric G. Cameron

Patent number: 6779156Abstract: According to the invention, a digital circuit design embodied in at least one of a structural netlist, a behavioral netlist, a hardware description language netlist, a full-custom ASIC, a semi-custom ASIC, an IP core, an integrated circuit, a hybrid of chips, one or more masks, a FPGA, and a circuit card assembly is disclosed. The digital circuit design includes first and second sub-circuits. The first sub-circuits comprise a first percentage of the digital circuit design and the second sub-circuits comprise a second percentage of the digital circuit design. Each of the second sub-circuits is substantially comprised of one or more kernel circuits. The kernel circuits are comprised of selection circuits. The second percentage is at least 5%. In various embodiments, the second percentage could be at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 95%.Type: GrantFiled: June 14, 2002Date of Patent: August 17, 2004Assignee: Science & Technology Corporation @ UNMInventors: Sterling R.

Patent number: 6779158Abstract: According to the invention, a digital design method for manipulating a digital circuit netlist is disclosed. In one step, a first netlist is loaded. The first netlist is comprised of first basic cells that are comprised of first kernel cells. The first netlist is manipulated to create a second netlist. The second netlist is comprised of second basic cells that are comprised of second kernel cells. A percentage of the first and second kernel cells are selection circuits. There is less chip area consumed in the second basic cells than in the first basic cells. The second netlist is stored. In various embodiments, the percentage could be 2% or more, 5% or more, 10% or more, 20% or more, 30% or more, or 40% or more.Type: GrantFiled: June 14, 2002Date of Patent: August 17, 2004Assignee: Science & Technology Corporation @ UNMInventors: Sterling R.
