Notes:
[7] The array distributed networks consist of 88 half columns and the global distributed networks
consist of 92 half columns, each driven by an independent buffer. The number of half columns
used does not affect clock buffer delay. The array clock has up to 18 loads per half column. The
global clock has up to 20 loads per half column.
[8] The following loads are used for tPXZ:
