Setting up the

Agilent Technologies 16700

Series Logic Analysis System

Take a Measurement with the ILA

Triggered From an External

Analyzer

We are going to use a simple 32-bit

binary counter to demonstrate the

ease of setting up and taking a meas-

urement using both the Agilent

Technologies and Xilinx logic analyz-

ers. The counter is probed internally

using the Xilinx ChipScope ILA and

externally with an Agilent 16752A

analysis module installed in a 16700

Series mainframe. We generated a 34-

bit analyzer using the tools on the

Xilinx website at www.xilinx.com to

directly probe the counter registers.

We will probe the same counter at the

chip I/O using an Agilent 16752A

logic analysis module in state mode.

The basic system setup used for this

example and any other type of com-

bined measurement is shown in

Figure 2. This diagram indicates the

type of connections necessary

between the different equipment to

achieve a correlated display.

We will set up an Agilent 16700 to

drive its external port out when the

trigger condition is met. We do this

from the main system window. Select

the “Port Out” button to bring up its

setup window (Figure 3). The port

will be unselected and will not drive

after system startup. We are select-

ing the analyzer in slot A as the arm-

ing analyzer for this example. You

could use any of the Agilent logic

analysis modules plugged into a

16700 Series mainframe for this pur-

pose. We enable the port as "Pulsed"

so that the output is only high for

awhile after trigger, but not prior to

trigger.
