  • Patent number: 10380294
    Abstract: The present disclosure relates to a computer-implemented method for simulating a circuit design having a discrete domain segment connected to a continuous domain segment at a connection point. The method may include inserting a bidirectional interface element at the connection point located between the discrete domain segment and the continuous domain segment. The method may also include splitting the discrete domain segment into a plurality of transistor network models to provide for bi-directional transfer of data between the continuous domain segment and the discrete domain segment, wherein at least one of the plurality of transistor network models utilizes only one or more drivers external to a module.

  • Patent number: 8401828
    Abstract: Systems and methods for simulating and verifying an analog mixed signal design provide an analog mixed signal testbench configured to verify analog parameters of the design. The testbench can include a mechanism to fetch a value of an analog object in an analog portion of a mixed signal design. The testbench mechanism can include an argument specifying the name of the object and the analog quantity to be fetched for that object. The testbench can retrieve estimated values and can further specify timing constraints specifying absolute times or events at which values are to be measured and returned.
