For optimizations like physical synthesis and static timing analysis, efficient interconnect delay and slew computation is critical. Since one cannot often afford to run asymptotic waveform evaluation (Pillage and Rohrer, 1990), constant time solutions are required. This work presents the first complete solution to closed-form formulas for both delay and also for slew. Our metrics are derived from matching circuit moments to the lognormal distribution. From a single table, one can easily… CONTINUE READING
