Timing Measurement Methodology

When measuring timing parameters at the programmable 
I/Os, different signal standards call for different test 
conditions. 

Table 26

 lists the conditions to use for each 

standard. 

The method for measuring Input timing is as follows: A 
signal that swings between a Low logic level of V

L

 and a 

High logic level of V

H

 is applied to the Input under test. 

Some standards also require the application of a bias 
voltage to the V

REF

 pins of a given bank to properly set the 

input-switching threshold. The measurement point of the 
Input signal (V

M

) is commonly located halfway between V

L

 

and V

H

.

The Output test setup is shown in 

Figure 8

. A termination 

voltage V

T

 is applied to the termination resistor R

T

, the other 

end of which is connected to the Output. For each standard, 
R

T

 and V

T

 generally take on the standard values 

recommended for minimizing signal reflections. If the 
standard does not ordinarily use terminations (for example, 

LVCMOS, LVTTL), then R

T 

is set to 1M

Ω

 to indicate an 

open connection, and V

T

 is set to zero. The same 

measurement point (V

M

) that was used at the Input is also 

used at the Output.
