Timing Measurement Methodology
When measuring timing parameters at the programmable I/Os, different signal standards call for different test conditions.
Table 27 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 VL and a High logic
level of VH is applied to the Input under test. Some standards also require the application of a bias voltage to the VREF pins
of a given bank to properly set the input-switching threshold. The measurement point of the Input signal (VM) is commonly
located halfway between VL and VH.
The Output test setup is shown in Figure 9. A termination voltage VT is applied to the termination resistor RT, the other end
of which is connected to the Output. For each standard, RT and VT generally take on the standard values recommended for
minimizing signal reflections. If the standard does not ordinarily use terminations (for example, LVCMOS, LVTTL), then RT
is set to 1 M
to indicate an open connection, and V
T is set to zero. The same measurement point (VM) that was used at the
Input is also used at the Output.
