Stochastic Interconnect Modeling and Transient Simulation in the Presence of Process Variations

摘要

The random process variations are always existent during manufacturing process, which has a definite impact on transmission performance of interconnects. Considering the impact the stochastic interconnect model is proposed, and the statistical analysis of the transient simulation, which is based on Monte Carlo method, is presented. During the analytical process the method on lines is applied to solve the transient simulation of each sample, and Jarque-Bera test is made to verify the normality of the output. Finally the worst-case estimation is given. Experimental results demonstrate that the proposed stochastic model and the corresponding statistical analysis method can evaluate the transmission performance of interconnects effectively, which is very significant for the control and optimization of interconnects' manufacturing process.
