Based on the equilibrium concept of inserting load in a physical balance, the insertion of redundant wires can be used to minimize the clock skew in an OPE-predicted clock tree. For five tested benchmarks, the experimental results show that our proposed algorithm only increases 2.8% of the total load on the average for the insertion of OPE-predicted redundant wires and decreases 30.85 ps of the clock...
Given a set of n IO buffers and a set of n bump balls on a re-distribution routing layer, an O(n(logn)2) routability-driven partition-based IO assignment is proposed to assign n IO connections for RDL routing in a flip-chip design. Firstly, based on the recursive partition of bump balls and IO buffers, the partition-based IO assignment can be obtained by using the geometrical mapping between bump...
In this paper, based on the optimality of hierarchical bubble sorting, the problem of two-sided single-detour untangling for single-layer bus routing is firstly formulated. Compared with an optimal O(n3) algorithm[4] for one-sided single-detour untangling without capacity consideration, an optimal O(n2) algorithm is proposed to solve the two-sided single-detour untangling problem without capacity...
