2.5.6. Vectorless Estimation Power Analysis Flow
Vectorless estimation statistically estimates the signal activity of a node based on the signal activities of nodes feeding that node, and on the actual logic function that the node implements. Vectorless estimation cannot derive signal activities for primary inputs. Vectorless estimation is accurate for combinational nodes, but not for registered nodes. Therefore, the Power Analyzer requires simulation data for at least the registered nodes and I/O nodes for accuracy.
