Large Scale Placement with Explicit Cell Movement Control

Nowadays a circuit placement algorithm often faces a problem size of multi-million objects, with excessive fixed blockages. We present a new efficient quadratic placement algorithm that scales well to the large-scale circuit placement problems. Instead of adding spreading forces into the quadratic system to push cells away from congestions, we simulate the cell diffusion process and use dummy a...

Quadratic Placement Revisited M1.3 : Methodology (techniques for Deep-submicron Placement)

The basic \quadratic placement" methodology is rooted in works by Wipper et al. 36], Cheng and Kuh 8], Tsay et al. 32, 33, 34] and many others. It is also, reputedly, an approach that has been used in commercial and in-house tools for placement of standard-cell and gate-array designs. The quadratic placement methodology entails (i) solving recursively generated sparse systems of linear equation...

Improving the Quadratic Objective Function in Module Placement

Traditional placement goals for cell-based designs involve minimizing either total wirelength or channel width; each of these metrics re ects nal layout area. Typically, a net model is rst used to transform the netlist hypergraph into a graph representation. A linear wirelength objective is then formulated, but then for technical reasons a quadratic form is actually optimized using relaxation o...

Quadratic Placement Revisited 1

The “quadratic placement” methodology is rooted in [6] [14] [16] and is reputedly used in many commercial and in-house tools for placement of standard-cell and gate-array designs. The methodology iterates between two basic steps: solving sparse systems of linear equations, and repartitioning. This work dissects the implementation and motivations for quadratic placement. We first show that (i) K...

Active vibration control of smart building frames by feedback controllers

In this paper the active vibration control of a four-story shear frame instrumented with piezoelectric actuators is presented. The piezoelectric actuators are hosted on the columns in two manners and the produced controlling forces by actuators are considered in the equation of motion. The smart structure modeling and control design is carried out using MATLAB software in state space form. Subs...
