Based on the assumption of a single wiring open in a signal net, it is known that the non-tree topology for a signal net has no adjacent loop. In this paper, based on RC non-tree transformation in Elmore delay model, an optimal algorithm for timing analysis is firstly proposed to compute the timing delays of all the reference nodes in a non-tree topology. Compared with the SPICE tool, the experimental...
For a given floorplan in hierarchical power quad-grids(HPQGs) with the IR-drop constraint and the electromigration constraint, an iterative two-phase approach is proposed to design reliability-driven HPQGs to assign limited power pads and power wires to supply the required current and satisfy the current density constraint for each power branch and the IR-drop constraint for each power node with minimizing...
In this paper, based on the topology of floorplan-aware hierarchical power quad-grids, an optimal network analysis method is proposed to accurately find the voltages of all the reference nodes and the currents of all the reference branches. For the wiring area assignment of floorplan-aware hierarchical power quad-grids, the experimental results show that the ILVCS approach (Yan, 2005) with our proposed...
