  • Patent number: 11354480
    Abstract: Various embodiments provide for determining clock gates for decloning based on simulation and a satisfiability solver, which can be part of electronic design automation (EDA). In particular, some embodiments use a simulation process to quickly determine whether enable signals associated with two clock gates are logically equivalent using a random input vector to a circuit design and, if logically equivalent by the simulation process, use a satisfiability solver to determine a variable assignment (e.g., at least one vector) such that the enable signals are found to be non-equivalent.

  • Patent number: 11354479
    Abstract: A system for performing operations including accessing an integrated circuit design that includes a clock tree interconnecting a clock source to a plurality of clock sinks. The operations include receiving a request to adjust a current timing offset of the clock tree to a target timing offset. The clock tree is modified by moving a terminal of the group from a first location in the clock tree to a second location in the clock tree to generate an updated clock tree. During modification, the first and second locations are analyzed to determine a load reduction and increase at the respective terminals. One or more neighboring clock tree instances are adjusted to compensate for the load reduction and increase. The operations include providing an indication that the clock tree has been updated and complies with the target timing offset.

  • Patent number: 11347919
    Abstract: A method for generating a fault tree of a multi-component system is provided. The multicomponent system includes a logical-functional system layer and a physical system layer as different layers of abstraction. The physical system layer may correspond, for example, to software and/or hardware implementing the functional aspects of the logical-functional system layer. The method first provides a logical-functional fault tree for the logical-functional system layer and a physical fault tree for the physical system layer, the latter having elements corresponding to elements in the logical-functional fault tree. Next, a mixed-layer fault tree is generated by combining aspects of both fault trees in a systematic way. The disclosed is particularly relevant for analyzing safety-critical systems. However, the present concepts are not limited to these applications and may be applied to general use cases where fault tree analysis is applicable.

  • Patent number: 11334702
    Abstract: A computing system implementing a design verification system can elaborate a mixed-signal circuit design having a complex sandwich hierarchy using a standard digital solver and a standard analog solver, as opposed to a tightly coupled custom elaboration engine. The design verification system can parse the mixed-signal circuit design to identify analog design blocks and flatten the analog design blocks into the structural proxy blocks having parameter connections to digital design blocks in the mixed-signal circuit design. The design verification system can replace an analog portion of the mixed-signal circuit design with the structural proxy blocks and elaborate the structural proxy blocks and digital design blocks associated with a digital portion of the mixed-signal circuit design. The design verification system can elaborate the analog portion of the mixed-signal design and simulate the elaborated analog portion with an analog simulator and the elaborated digital portion with a digital simulator.

  • Patent number: 11334698
    Abstract: Disclosed is cell-aware defect characterization by considering inter-cell timing. Also disclosed is a method and apparatus that determines whether a defect can be detected in a standard library cell used to design an integrated circuit. A defect detection table is generated that indicates whether particular defects can be detected with particular combinations of input logic states and under varying load conditions. Results are merged to provide a single metric for each combination of input and output logic states that indicates one of three possible results for each defect: (1) whether the defect can be detected under all load conditions, (2) whether the defect can be detected only under some load conditions; or (3) whether the defect cannot be detected for the particular combination of input logic states regardless of the load conditions.

  • Patent number: 11321511
    Abstract: Systems and methods are disclosed for generation and testing of integrated circuit designs with clock crossings between clock domains and reset crossings between reset domains. These may allow for the rapid design and testing (e.g. silicon testing) of processors and SoCs. Clock crossings may be automatically generated between modules, inferring the values of design parameters, such as a signaling protocol (e.g. a bus protocol), directionality, and/or a clock crossing type (e.g., synchronous, rational divider, or asynchronous), of a clock crossing. Reset crossings may be automatically generated in a similar manner. For example, implicit classes may be used to generate clock crossings or reset crossings in a flexible manner. For example, these system and methods may be used to rapidly connect a custom processor design, including one or more IP cores, to a standard input/output shell for a SoC design to facilitate rapid silicon testing of the custom processor design.
