....arrays are usually very sparse, a considerable area reduction can be achieved by folding. If we restrict the folding to pairs of columns, simple folding is obtained; if no restrictions are imposed, the folding is multiple. The problem of optimum PLA folding is discussed extensively in literature [1 3]. Also, design ideas for the problem of multiple folding of PLAs apply to the gate matrix layout problem [3] The folding problem has been shown to be NPcomplete [4] Consequently most efforts have been made in the search of heuristic algorithms. Here, we transform the problem of simple or ....

The folding problem has been shown to be NPcomplete [4] Consequently most efforts have been made in the search of heuristic algorithms. Here, we transform the problem of simple or multiple column folding into one of boolean satisfiability in a similar way to [5] for the problem of optimal ....
