Notes to

Table 5–16:

(1) Delay numbers for t

GLOB

differ for each device density and speed grade. The delay numbers for t

GLOB

, shown in

Table 5–16,

are based on an EPM240

device target.

(2) Refer to

Table 5–32

and

5–24

for delay adders associated with different I/O standards, drive strengths, and slew rates.

(3) Refer to

Table 5–19

and

5–14

for t

delay adders associated with different I/O standards, drive strengths, and slew rates.

(4) Refer to

Table 5–17

and

5–13

for t

delay adders associated with different I/O standards, drive strengths, and slew rates.

Table 5–17

through

Table 5–20

show the adder delays for t

and t

microparameters

when using an I/O standard other than 3.3-V LVTTL with 16 mA drive strength.
