in this training manual. The exercises rely on a single setup of the training board.
Hardware Setups
Connect the P6418 or P6417 probe to the C2/C3 connector on the logic analyzer
module. You will use the same probe connections through the remainder of this
chapter. If you have an oscilloscope module (DSO), connect an oscilloscope
probe to Channel 1 of the DSO module.
Set up the P6417 Probes
Depending on the number of your logic analyzer probes, you may need to
reconfigure your probes. The following sections provide basic probe setup
information.
Removing Podlets
To complete the exercises in this section, you must remove and separate the
P6417 probe podlets from the podlet holder. Refer to Figure 2–1 and open the
podlet holder as shown and remove the podlets one at a time.

Reinstalling Podlets
Connect the Probes
When reinstalling the podlets, make sure all the ground sides of the podlets line
up with the ground side of the podlet connector. Arrange the podlets by their
color-coded rings; use the key on the reverse side of the podlet holder to place
the podlets in the correct channel order.
Complete the following steps to connect the logic analyzer probes to the training
board. If you are using the P6418 probes, use the flying lead sets and refer to
Figure 2–2 while connecting the probes; if you are using the P6417 probes, refer
to Figure 2–3 while connecting the probes to the training board. Make sure that
you connect the signal side of the probes to signal side of the square pins
(ground signals are toward the rear of the training board as you face the LCD
display).
1. Connect the clock channel (CK3) of the C2-C3 probe to J760 (CNTR CLK)
on the training board.
2. Connect the C2:0, C2:1, C2:2 probe podlets of the C2-C3 probe to J860 on
the training board.
3. Connect the Channel 1 oscilloscope probe to the unused J860 signal square
pin labeled FF-Q.

Load the Setups
Perform the following steps to load the timing exercises. All timing exercises are
contained in the same folder (C:\Program Files\TLA 700\Quick Start\Hardware
Analysis).
NOTE. Each exercise contains two saved setup files. One file contains only setup
information and requires you to capture live acquisition data to complete the
exercises. The other file contains setup information and saved data. Use the
saved data files to complete nearly every exercise without the need for acquiring
live data.
You can also use TLAVu to complete the exercises off-line without needing any
acquisition hardware.
1. Select Load System from the File menu.
2. Open the Workbook folder and select the file as defined in the individual
exercises (for example, load the 1-Capture and Trigger on a Glitch.tla file for
Exercise 1).
The logic analyzer display should look similar to Figure 2–4.

3. When prompted to load without saving the current system, click on Yes.
4. If you get a message telling you that the configuration in the file does not
match your current hardware, click on OK. A new dialog box appears.
a. Drag the “My Analyzer” icon (and the “My DSO” icon, if needed) from
the top of the window to the shaded LA1 icon in the Current System
window.
b. Click on OK to continue with the exercise.
NOTE. If the Load System Options dialog box appears and you want to view
saved data, you may need to complete steps 5 through 8 to load a data window
with saved acquisition data.
To determine if you need to perform the following steps, click on one of the data
window icons. If data appears in the data window, you can continue with the
exercise. If no data appears, complete the following steps after you complete
step 4 above.
5. Select Load Data Window from the Window menu; the Load Data Window
dialog box displays.
6. Click the Browse button, navigate to the Hardware Analysis setup folder,
and then double-click the setup for the current exercise.
7. Select the data window from the list in the Load Data Window dialog and
then click OK; the Name Data Window dialog box displays.
8. Change the name of the data window (it is recommended that you only
change one or two characters so the name is similar to the original data
window).
Now you have a data window that displays saved acquisition data for the current
exercise. If you want to continue with the exercise and capture live data, refer
back to the original data window that was loaded with the setup.

Exercise Overview
These exercises focus on a metastable problem caused by driving the clock input
of a flip-flop with a 50 MHz clock and the D input (FF-D) with an asynchronous
10 MHz data stream. Under these conditions the setup and hold times of the
flip-flop are often violated. When the violation occurs, the output of the flip-flop
goes into a potentially metastable state.
When the flip-flop is in a metastable state, the outputs are unpredictable. This
can result in the flip-flop producing a glitch (the output pulse is shorter than
normal), the outputs could briefly oscillate, or the outputs may not change at all.
These type of failures are usually intermittent and can be difficult to find.
The key to isolating these kinds of timing faults is to trigger the logic analyzer
when the Q output (FF-Q) of a flip-flop has a shorter pulse width than the period
of the driving clock signal (FF-CLK). When an edge-triggered flip-flop works
properly, the minimum time between changes on the Q output must be equal to
or greater than the driving clock period.
The device used in these exercises is a 74F174 flip-flop with the specifications in
Table 2–1. The training board provides connections to the flip-flop (see
Figure 2–2 on page 2–2 or Figure on 2–3 page 2–3).
