Commercial crosstalk analysis tools are widely used for timing verification of LSI, but they analyze the worst case of crosstalk effect in any theoretical cases, which is really pessimistic. Some works have been done to reduce the pessimism based on deterministic method like logical correlation or timing window correlation. In this paper, a novel and practical crosstalk analysis introducing probability of simultaneous multiple aggressors' noise injection timing into crosstalk analysis methods with not only net based but also path based profiling is proposed. With the methods more than 50% pessimism reduction can be obtained in addition to net based approach.
