Cyclone FPGA Family Data Sheet
Preliminary Information
Tables 59 through 64 show the adder delays associated with column and
row I/O pins for all packages. If an I/O standard is selected other than
LVTTL 24 mA with a fast slew rate, add the selected delay to the external
tCO and tSU I/O parameters shown in Tables 44 through 47.
