Notes:
1. Listed above are 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. PLL output jitter is included in the timing calculation.

Notes:
1. Listed above are 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. DCM and PLL output jitter are already included in the timing calculation.
