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
