VLSI Cell Placement Techniques

Algorithm for Block Placement by Size Optimization

This approach selects the optimal block size and relative block placement repeatedly in order to eliminate wasted space and reduce total chip area. During the optimization process, channel widths are also taken into account.

Simulated Annealing — TimberWolf (Part 1–2).

An overview to the Timber Wolf Algorithm.

Energy function minimization model

KK algorithm

The KK algorithm places nodes in the picture so that their apparent distance is proportional to their theoretical graphed distance. Because this aim cannot always be reached for arbitrary network topologies, the…

PLACEMENT BY PARTITIONING

Cut Oriented Min-Cut Placement Algorithm: Begin by cutting a series of cut lines around the entire chip. Allow the…

VLSI Cell Placement Techniques

PROUD: Placement by Block Gauss-Seidel Optimization

The module placement problem involves placing a set of modules (standard cells, gate arrays, sea-of-gates) on a VLSI chip, given a netlist that specifies the connectivity between the modules. The…
