Closed-form solution for timing analysis of process variations on SWCNT interconnect

In this paper, a comprehensive and fast method is presented for the timing analysis of process variations on single-walled carbon nanotube (SWCNT) bundles. Unlike previous works that based on SPICE tools to estimate the delay, this paper proposes a closed-form solution for SWCNT interconnect timing analysis. With the assumption that the process variations are independent random variables, the delay of SWCNT bundles are mapped to a linear function of the variation variables, and efficiently calculated in the form of probability density functions (PDFs). Compared to SPICEbased solutions, this approach not only saves considerable computation time, but also provides a more comprehensive result, for it shows a compound impact of all variations, and covers all of the potential cases with their corresponding probabilities, rather than only one parameter can vary at a time, and only a worst case estimation is considered. The experiment results show that this solution bears little loss while p...
