  • Patent number: 11356275
    Abstract: A method verifies an authenticity, integrity, and provenance of outputs from steps in a process flow. One or more processor(s) validate one or more inputs to each step in a process flow by verifying at least one of a hash and a digital signature of each of the one or more inputs. The processor(s) then generate digital signatures that cover outputs of each step and the one or more inputs to each step, such that the digital signatures result in a chain of digital signatures that are used to verify an authenticity, an integrity and a provenance of outputs of the one or more steps in the process flow.

  • Patent number: 11087062
    Abstract: Techniques for dynamically generating self-aligned double patterning (SADP) gate regions based on gate distribution and the relocation of the gates to their matched region are provided. In one aspect, a method for generating SADP gate regions in a circuit design includes: obtaining a circuit design having SADP gates, and a placement solution for the SADP gates that, while non-overlapping, violates SADP track routing matching requirements; determining approximate locations of SADP regions in the circuit design; assigning the SADP gates to the SADP regions using a minimum-cost maximum-flow (min-cost max-flow) process; and identifying, once all of the SADP gates have been assigned to the SADP regions, non-overlapping locations for the SADP gates in the SADP regions.

  • Patent number: 11074379
    Abstract: For each of a plurality of source-sink pairs, a corresponding interconnect layer is selected having a reach length which permits propagation of a required signal within a required sink cycle delay. For a first clock cycle, a movable region for a first latch is located as a first plurality of overlapped regions one reach length from a source and the required sink cycle delay number of reach lengths from each one of the sinks; and the first plurality of overlapped regions is represented as nodes on a first cycle level of a topology search graph. Analogous actions are carried out for a second clock cycle of the required sink cycle delay. A latch tree is created based on the topology search graph, wherein a required number of latches is minimized, and at each of the cycle levels, all sinks of source nodes selected at a previous level are covered.
