| 1. A method comprising:
grouping cells with similar topological characteristics into a family of cells, the topological characteristics being defined
in part by topological layouts of transistors in the respective cells in the family of cells; and
computing by a computer, data characterizing a relationship between a variability of delay and a magnitude of delay shared
among the cells in the family of cells.
