Notes:

1.This table lists representative values where one global clock input drives one vertical clock line in each accessible column, and where all accessible IOB and CLB flip-flops are clocked by the global clock net.

2.Refer to the Die Level Bank Numbering Overview section of the 7 Series FPGA Packaging and Pinout Specification (UG475) [Ref 4].
