Long Delay

Figure 1-35: Enlarging the clock pattern and speeding up the hardware clock
The pattern is displaced backward by three patterns so that the hardware delay is
1.5 ns. This causes a delay of 9 ns.
Figure 1-36: Obtaining a long delay
The Data Generator mode allows you to toggle Long Delay on or off in the Timing
window. In the Pulse Generator mode, Long Delay is always enabled internally.
Therefore it does not have a Long Delay On or Off setting.
Table 1-18 summarizes the characteristics of Long Delay.
Hardware clock period = 5 ns
User-defined clock period = 5 ns
Hardware clock period = 2.5 ns
User-defined clock period = 5 ns

Hardware clock period = 2.5 ns
User-defined clock period = 5 ns
Three patterns shift produces a delay of 7.5 ns; the hardware delay produces a delay of 1.5 ns.
This causes a total delay of 9 ns.
