An LSI compaction method which minimizes total wire length as well as layout area is discussed. First, the compaction problem is formulated as a linear programming problem and reduced to a problem involving finding a tree which has some properties in a constraint graph. Then, a method which finds the tree by a sequence of elementary tree transformations in the graph is proposed. It corresponds to the primal simplex method for LP. However, the proposed method is much more efficient, because it does not deal with any matrices in solving the problem.
