Output Delay Measurements
Output delays are measured using a Tektronix P6245
TDS500/600 probe (< 1 pF) across approximately 4" of FR4
microstrip trace. Standard termination was used for all
testing. The propagation delay of the 4" trace is
characterized separately and subtracted from the final
measurement, and is therefore not included in the
generalized test setups shown in Figure 4 and Figure 5.
Measurements and test conditions are reflected in the IBIS
models except where the IBIS format precludes it.
Parameters VREF, RREF, CREF, and VMEAS fully describe
the test conditions for each I/O standard. The most accurate
prediction of propagation delay in any given application can
be obtained through IBIS simulation, using the following
method:
1.
Simulate the output driver of choice into the generalized
test setup, using values from Table 32.
2.
Record the time to VMEAS.
3.
Simulate the output driver of choice into the actual PCB
trace and load, using the appropriate IBIS model or
capacitance value to represent the load.
4.
Record the time to VMEAS.
5.
Compare the results of steps 2 and 4. The increase or
decrease in delay yields the actual propagation delay of
the PCB trace.
