BUFIOSKEW
Symbol
LXT devices are not available with a -1L speed grade. The LX4 is not available in -3N speed grade.
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.
The T
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.
CKSKEW
I/O clock tree skew across one clock region
value represents the worst-case clock-tree skew observable between sequential I/O elements. Significantly less clock-tree skew exists
