In this paper, we address the problem of signal pruning in static timing analysis (STA). Traditionally, signals are propagated through the circuit and are pruned, such that only the signal with the latest arrival time at each node is propagated forward. This sig-nal pruning is a key to the linear run time of STA. However, it was previously observed that a signal with the latest arrival time may not be the most critical signal, as an earlier signal with a larger transition time can result in a… CONTINUE READING
