FPGA dynamic probe lets you:

View internal activity – With the

digital channels on your MSO, you

are normally limited to measuring

signals at the periphery of the

FPGA. With the FPGA dynamic

probe, you can now access signals

internal to the FPGA. You can

measure up to 256 internal

signals for each external pin

dedicated to debug, unlocking

visibility into your design that

you never had before.

Make multiple measurements in

seconds – Moving probe points

internal to an FPGA used to be

time consuming. Now, in less than

a second, you can easily measure

different sets of internal signals

without design changes. FPGA

timing stays constant when you

select new sets of internal signals

for probing.

Leverage the work you did in your

design environment – The FPGA

dynamic probe maps internal

signal names from your FPGA

design tool to your Agilent MSO.

Eliminate unintentional mistakes

and save hours of time with this

automatic setup of signal and bus

names on your MSO.

Figure 2. The FPGA dynamic probe requires Altera’s Quartus II design software

with its LAI (logic analyzer interface) and Altera programming hardware setup.

The Quartus II (ver. 6.0 or higher) LAI allows you to create and insert a debug core

that interacts with the FPGA dynamic probe application on your MSO. The FPGA

dynamic probe controls which group of internal signals to measure via the Altera

programming hardware connected to the JTAG port of the FPGA.

Figure 3: Access up to 256 internal signals for each debug pin. Signal banks

all have identical width (1 to 256 signals wide) determined by the number

of device pins you devote for debug. MSO8000 series can acquire up to 16

signals using digital channels. Each pin provides sequential access to one

signal from every input bank.
