Abstract

As the technology advances into deep sub-micron era, crosstalk reduction is of paramount importance for signal integrity. Simultaneous shield insertion and net ordering (SINO) has been shown to be effective to reduce both capacitive and inductive couplings. As it introduces extra shields, area minimization is also critical for an efficient SINO algorithm. In this paper, three novel algorithms using fewer shields to solve crosstalk reduction problem with RLC noise constraint are proposed, namely, net coloring (NC), efficient middle shield insertion (EMSI) and NC+EMSI two-step algorithm. Compared with the corresponding algorithms in previous work, these algorithms can reduce shielding area up to 25.77%, 46.19%, and 7.17%, respectively, with short runtime.
