Notes:
[7]The array distributed networks consist of 40 half columns and the global distributed networks consist of 44
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 8 loads per half column. The global clock has up to 11 loads
per half column.
