a. The array distributed networks consist of 40 half columns and the global distributed networks con-
sist 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.
