Abstract
- This paper considers the topological via minimization problem in the permutation layout, under the constraint that no wire passes between pins which are adjacent on the same horizontal line. Under a constraint that the upper side of the upper horizontal line not be used as the wiring area, an algorithm is proposed with time complexity (n² log n) for k = 1 and O(n3k-1) for the general value of k, for the problem of determining the set of maximum k-layer wiring (n is the number of nets). Then an algorithm is proposed with time complexity O(8kn3k-1) for the case where the wiring can be the whole plane. [ABSTRACT FROM AUTHOR]
