    摘要: A method and system for testing a circuit design. The method including generating a simulation model of the circuit design, the circuit design comprising one or more source latches, one or more destination latches and a logic function connected between the source latches and the destination latches; generating a modified simulation model of the simulation model by inserting random skew between an output of each source latch and an input of the logic function only in asynchronous data paths between the source latches and the destination latches of the simulation model; and running the modified simulation model.

    摘要: A digital circuit simulation method. The method starts with a digital circuit design which includes: a first source latch, a destination latch, a logic cone, a first WAM circuit electrically coupling an output of the first source latch to a first input of the logic cone, and a WAGG circuit electrically coupling an output of the logic cone and an input of the first source latch. Then, a zero-delay simulation is performed in which if a first situation of (a) the first WAM circuit entering an uncertainty state in which the first WAM circuit generates a random value of 1 or 0 at the first input of the logic cone, (b) the logic cone being vulnerable to a positive glitch, and (c) the output of the logic cone being at logic 0, the WAGG circuit generates a random value of 0 or 1 at input of the destination latch.
