reference (K) going to the high (H) state or setup time. Also, t
the time data input signals (D) went invalid (X) relative to the t
Note that, in general, the clock reference symbol representation is based on three letters representing the clock of a particular
functional. For example, the subscript of t
convention is used with the appropriate letter: R (rise) or F (fall).
