We bring up the ChipScope software

and set up the trigger condition as

"macro" with EXT as the source. In

addition, the capture mode is set up

as "One Shot" (default). We enable

the “Ext. Out” signal for synchroniza-

tion purposes (we are probing this

signal with both analyzers). The ILA

is now set up to trigger when its

external trigger input goes high.

Starting the ILA at this point will

arm it and force it to wait for the

16700 Series system to trigger.

Figure 8 shows the trigger position at

128 (out of 256 samples). The user

can set the trigger to any valid loca-

tion. The example screen also drives

the external trigger-out signal even

though the unit is not triggering any

other analyzers. This signal will be

used to correlate the data sets from

the Xilinx ILA and the Agilent logic

analysis module.

Take the Measurement

The Xilinx ILA can now be started

from the ChipScope interface. It will

arm and wait for the trigger from the

Agilent analysis module. The Agilent

16700 Series can then be started.

Once its trigger condition is detected,

both the Xilinx ILA and Agilent

16700 Series system will finish and

display data. Figures 9 and 10 show

both analyzers having completed an

acquisition.
