Notes:
1.
These parameters represent the worst-case duty cycle distortion observable at the pins of the device using LVDS output buffers. For cases
where other I/O standards are used, IBIS can be used to calculate any additional duty cycle distortion that might be caused by asymmetrical
rise/fall times.
2.
The TCKSKEW value represents the worst-case clock-tree skew observable between sequential I/O elements. Significantly less clock-tree
skew exists for I/O registers that are close to each other and fed by the same or adjacent clock-tree branches. Use the Xilinx FPGA_Editor
and Timing Analyzer tools to evaluate clock skew specific to your application.

Notes:
1.
These values represent the worst-case skew between any two SelectIO resources in the package: shortest flight time to longest flight time
from Pad to Ball (7.0 ps per mm).
2.
Package trace length information is available for these device/package combinations. This information can be used to deskew the package.
