      An n-leaf pipelined balanced binary tree is used for arbitration of order and movement of data from n input ports to one output port. A novel arbitrate-and-move primitive circuit for every node of the tree, which is ...
    • The Associative-Skew Clock Routing Problem 

      Chen, Yu; Kahng, Andrew B.; Qu, Gang; Zelikovsky, Alexander (IEEE, 1999-11)
      We introduce the associative skew clock routing problem, which seeks a clock routing tree such that zero skew is preserved only within identified groups of sinks. The associative skew problem is easier to address within ...
