An Enhanced Q-Sequence Augmented with Empty-Room-Insertion and Parenthesis Trees
Paris, France
March 04-March 08
ISBN: 0-7695-1471-5
After the discussion on the difference between floorplanning and packing in VLSI placement design, this paper adapts the floorplanner that is based on the Q-sequence to a packing algorithm. For the purpose, some empty room insertion is required to guarantee not to miss the optimum packing. To increase the performance in packing, a new move that perturbs the floorplan is introduced in terms of the Parenthesis-Tree Pair. A Simulated Anealing based packing search algorithm was implemented. Experimental results showed the effect of empty room insertion.
