representing the clock of a particular functional. For example, the subscript of t
clock. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall). For symbols
representing skews, the subscript is skew (SK) followed by the clock that is being skewed (TRX).
