Certified timing verification and the transition delay of a logic circuit
Srinivas Devadas, Kurt Keutzer, Sharad Malik, A. Wang · 2003
The transition delay of a circuit is examined. It is shown that the transition delay of a circuit can differ from the floating delay even in the presence of arbitrary monotonic speedups in the circuit. This result is used to derive a procedure which directly computes the transition delay of a circuit. Experimental results of applying the transition delay computation procedure to a number of benchmark examples are given. The most practical benefit of this procedure is that it not only results in a delay calculation but also produces a vector sequence that may be timing simulated to certify static timing verification.>
