Manufacturing hotspots are the layout patterns which cause excessive difficulties to manufacturing process. Design rules are effective at handling sizing/spacing induced hotspots, but are inadequate at dealing with topological hotspots. In wire routings, existing approaches often remove the hotspots through iteratively ripping up and rerouting one net at a time guided by litho-simulations. This procedure...
The three-dimensional (3D) integration circuit is a new technology with higher integration density. To solve the critical thermal issue in 3D layout, we propose a thermal-driven force-directed floorplanning algorithm. Based on the characteristic of the different stages of floorplanning, this algorithm applies different methods to calculate the thermal distribution to reach a tradeoff between time...
In this paper, we look at building robust on-chip power/ground (P/G) networks subject to limited routing resource, which becomes an important, yet challenging problem in nanometer VLSI design. We propose a novel method to size P/G wire widths of non-uniform P/G networks to minimize the worst-case static IR-drop. Our contributions consist of the following: (1) we propose an efficient worst-case IR-drop...
In this paper, an efficient mixed-mode placement algorithm called MMP is presented for the high performance mixed block and standard cell designs. Our approach combines the well-known quadratic placement with bottom-up clustering, as well as the slicing partitioning strategy. This approach can account for macro blocks and standard cells simultaneously. Our method is both very efficient and effective,...
