Notes:
1. The symbols used for timing specifications herein follow the pattern t(first two letters of functional block)(signal)(state) (reference)(state)
for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tGTKHDV symbolizes GMII
transmit timing (GT) with respect to the tGTX clock reference (K) going to the high state (H) relative to the time date input
signals (D) reaching the valid state (V) to state or setup time. Also, tGTKHDX symbolizes GMII transmit timing (GT) with respect
to the tGTX clock reference (K) going to the high state (H) relative to the time date input signals (D) going invalid (X) or hold
time. 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 tGTX represents the GMII(G) transmit (TX) clock. For rise and fall times,
the latter convention is used with the appropriate letter: R (rise) or F (fall).
