Using the Agilent Technologies 16700

Series Logic Analysis System with the

Xilinx ChipScope ILA

Product Note

This product note describes the abili-

ty to combine internal and

external logic analysis traces in a

time-correlated display on an Agilent

Technologies 16700 Series logic

analysis system. Agilent

Technologies provides logic analysis

capability for externally accessible

signals. The Xilinx ChipScope ILA

(integrated logic analyzer) "probes"

internal signals of a Field

Programmable Gate Array (FPGA).

Using the two tools together provides

digital design engineers with a pow-

erful system debug solution that

enables them to spend less time veri-

fying chip functionality. No longer

are designers forced to use a simula-

tor to examine the state of internal

nodes and attempt to correlate those

results to captured data on a logic

analyzer.

Initial Setup Requirements

Agilent Technologies Xilinx Target System

16700 Series Mainframe ChipScope ILA Software Headers or test

points

167xx Analyzer Module Virtex, VirtexE or Spartan FPGA devices JTAG port for

MultiLinx cable

ILA Tool Xilinx Internal Analyzer Modules

MultiLinx Cable

The user must have test points,

headers or devices with packaging

that can be probed on the circuit

board. Figure 1 shows different

methods of probing a circuit board.

For probing information, refer to

publication “Probing Solutions for

Agilent Logic Analysis Systems,”

5968-4632E. The key here is that

debugging capability requires access

to the signals of interest. Once the

ability to physically probe the target

system exists, the user can use a

16700 Series logic analysis system to

capture and analyze data. You will

need the ILA correlation software

tool installed on the 16700. This tool

is available with version A.02.10.00

or higher.

You also need Xilinx (Virtex, VirtexE

or Spartan II) devices to use the

Xilinx ChipScope ILA. Figure 1

shows a board with Xilinx Virtex

devices installed. You will need two

free pins on the FPGA package that

can be probed for trigger-in and trig-

ger-out functions.

The Xilinx ChipScope ILA provides a

means to probe signals internal to the

Virtex families of FPGA devices. This

ILA can be configured to receive a

trigger from an external source and

drive a signal to trigger external

equipment. We will use this capabili-

ty along with the "Port In" and “Port

Out" functions of the 16700 Series

logic analysis system to perform cor-

related measurements with both

Xilinx and Agilent logic analyzers.
