The numbers in this table are based on the operating conditions set forth in
Symbol
When reading from the FFX (FFY) Flip-Flop, the time
from the active transition at the CLK input to data
appearing at the XQ (YQ) output
Time from the setup of data at the F or G input to the
active transition at the CLK input of the CLB
Time from the setup of data at the BX or BY input to
the active transition at the CLK input of the CLB
Time from the active transition at the CLK input to the
point where data is last held at the F or G input
Time from the active transition at the CLK input to the
point where data is last held at the BX or BY input
The High pulse width of the CLB’s CLK signal
The Low pulse width of the CLK signal
Toggle frequency (for export control)
The time it takes for data to travel from the CLB’s
F (G) input to the X (Y) output
The minimum allowable pulse width, High or Low, to
the CLB’s SR input
