ABSTRACT
IBM PC BASED SO ·MHZ LOGIC ANALYZER
by
Jin-Hwa Chen
Master of Science in Engineering
The objective of this project is to design and develop
a SO MHz logic analyzer which can automatically acquire
sampled data after setting required functions.
The logic
analyzer will provide the user with the means of developing
and debugging a newly designed circuitry and repairing a
improper functioned circuitry.
The logic analyzer is
flexible and relatively easy to use so that a diversified
number of needs and requirements can be met and satisfied.
In addition, the analyzer is very convenient for the user
since it uses the input and output interfaces of an IBM PC
to input commands and display results.
The sampling clock rate is selectable and has a range
from 2S KHz to SO MHZ.
Up to a maximum of 24 channels can
be used simultaneously and it can store up to 1024 words in
the memory.
Both timing and state functions are provided
so that the user can have a very good interpretation of the
acquired data.
The analyzer was designed and constructed.
results indicated that it performed properly.

CHAPTER 1
INTRODUCTION
Rapid advances in large scale integration technology
enable engineers build equipment capa·ble of performing
larger and larger logic functions.
In designing the
equipment, it has become extremely difficult for an
engineer to analyze and debug the equipment.
Although oscilloscopes still play an important role in
circuit analysis, they are more useful on the analog
circuits than on the digital circuits.
contains many digital circuits.
Digital equipment
Each circuit must produce
a proper sequence of signals in synchronism with the
outputs of the other circuits.
In order to verify that a
circuit is operating properly, its output waveform and
outputs waveforms of other circuits must be observed at the
same time.
Circuits involved memories, address
information, data bus 1nfozmation and information on
various part of the system must be examined over several
memory cycles.
Occurrences of fault conditions can be
detected by looking backward in time over the memory
cycles.
This project involves the design of a logic analyzer
to be interfaced with an IBM PC.
The analyzer is capable
of receiving and displaying up to 24 data channels at the
sampling rate up to 50 HHz.
1
The sampled data are stored in
2
the memory, processed and displayed on the monitor in
binary form, hexadecimal form, decimal form, or timing
diagram.
Also, the data can be stored in the diskette by
specifying a certain file name and can be retrieved later.
CHAPTER 2
HARDWARE OESIGN
2.1
Clock Generation
The clocks generated by the circuit are 50 MHz, 5 MHz,
1MHz, 500KHz, 100 KHz, 50 KHz, and 25 KHz.
A 50 KHz
crystal and a 74F04 inverter gate are used to generate the
50 MHz clock.
Due to the large time constant of the
inverter gate, a emitter follower is used to reduce time
constant to generate a 50 MHz clock with sharp leading and
trailing edges.
A 74F74 Flip-Flop gate is used to divide the 50 MHz
clock by two to generate a 25 MHz clock.
The 25 HHz clock
is fed into a 16R8 PAL to be divided by 5 or 25 to generate
a 5 MHz or 1 HHz clock.
The 1 MHz output is further fed
into a 16R8 PAL to be divided by 2, 10, 20, or 40 to
generate a 500 KHz, 100 KHz, 50 KHz, or 25 KHz clock.
action is controlled by a 8255 PPI through software.
The
A
78L05 power regulator is used to make the clock more
stable.
2.2
Input Buffering
Up to 24 channels of signals can be connected to the
analyzer.
Three cables with 28 clippers
~re
used for the
transmission of the signals.
There are two problems occur in the transaission of
3
4
high frequency signals.
First, the stray capacitor causes
coupling between two transmission lines to produce
crosstalk.
This problem can be solved by shielding each of
the lines.
The shieldings are then grounded to isolate the
signals.
The second problem is that there exists a voltage
difference between two ends of a line, due to the
inductance of the line.
To deal with this problem, the
input impedance is matched by the use of an input buffering
circuit.
Three 74F374s, octal D-type edge triggered flip-flops
with tri-state output buffers, are used as input buffering
circuit.
Also three 100 K Ohm resistor arrays are used to
increase the input impedance.
A 74F251 multiplexer is used
to gate the internal or external clock to the 74F374 flipflops.
The clock is used as triggering clock for the flip-
flops to latch the incoming signals.
As
to which of the
clocks will be used is controlled by 8255 PPI through
software.
The external clock is inputted to a 74F86 XOR gate to
form the external clock used by the analyzer.
A 100 K Ohm
resister is used to increase the input impedance of the
74F86 gate.
The 74F86 gate is also controlled by the 8255
PPI through software to specify the triggering edge of the
external clock.
5
2.3
Data Storage
There are total 24 channels.
1024 events each
channel can be stored in the memory to be processed.
The
analyzer has to process signal up to 50 MHz, which is
equivalent to process data within 20 nano-second.
The IBM
PC XT or AT with operating speed of only 8 MHz can not be
used to process the data.
A~thod
of
~rocessing
the data
in re.al time involved the design of high speed hardware.
High speed RAMs are used and the address for these RAMs are
generated by high speed counters to achieve the data
processing requirement.
Six 2148s, 1024 X 4 high speed static RAMs, are used
to store the acquired data and are capable of storing data
up to 1024 X 24 words.
The access time for the 2148 is 20
nano-second.
Three 74F161s, high speed counters, are used to
generate the address of the 2148 RAMs.
These three
counters are cascading together so that they can count up
to 4096.
Since only 1024 counts are needed, the last two
bits of the last
co~nter
are ignored.
The counters are
triggered by the output of a 74F251 multiplexer .which gates
the selected clock rate through a 74F04 inverter to form
low to high pulses for the rising edge triggered counters.
The output enable of the_ 74F374 flip-flops and the
write enable of ·the 2148 RAMs are connected together to
enable the latched data be written to the memory.
This
control line is active when a trigger word is matched.
6
2.4
Generation of Trigger Position
The trigger position can be set at any multiple of 64
boundary within the 1024 memory locations.
When debugging a system, condi-tions after trigger
point and conditions prior to the trigger point must be
known.
With this in mind, a circuit was designed to allow
the viewing of different length of pre-trigger data and
post-trigger data.
Three 74F161s, counters with pre-load capability, are
used to fulfill this requirement.
These counters are pre-
loaded with trigger position value which is controlled by
the 8255 PPI.
As long as the trigger condition is met,
these counters start to count up with the clock from the
74F251 multiplexer.
At the beginning, when the trigger
condition is satisfied, the outputs of these counters are
not all "high" which causes the output of the 748134 gate
"high".
Through an inverter, this output becomes "low"
which is used to enable the latched data to be written into
memory.
After these counters count up to all "high", the
output of 748134 gate becomes "low" which will disable
74F374 flip-flops to output the latched data.
Data is
prevented from written into the 2148 RAMs. At .this· moment,
the counters continue to count up.
A command is issued
from the 8255 PPI to disable the 748134 qate.
After the
74S134 gate is disabled, it will become floating.
A 330
Ohm resistor is used to pull the output to "low" to ensure
the proper operation.
A 47 pf capacitor is used at this
1
point to minimize hiqh frequency noise.
2.5
Generation of Trigger Word
All 24 channels of the analyzer can be set to a
trigger condition of "1", "0", or "don't care".
After the
trigger condition is met, the counters will start to count
for a certain length of time according to the trigger
position.
The trigger word selected by the user is using as
address to set the corresponding location to "1" and all
other locations to "O".
The "don't care" bit is cleared to
"0" for the address generation.
When the incoming word is
the same as the trigger word, the memory outputs the preset
"1" to start the proper operations.
Two 2141s, 4096 X 1 static RAMs, are used to set
trigger word.
The trigger word location is set to "1"
through the 8255 PPI by software.
of each 2141 is 12.
The address line number
With two 2147 RAMs, 24-bit trigger
words can be recorded.
When the incoming word matches with the selected
trigger word, both the 2147 RAMs will output "1" to start
proper operation.
Twenty four 21 Ohm resisters are used to
prevent the damage of 8255 PPI and 74F374 flip-flops when
both of them are in output mode.
8
2.6
Control Signals Interface
Two 8255 PPis are used to generate all the control
signals and the trigger word through software controls.
A
PAL is used to decode the I/O address for inputting the
counters' condition to the IBH PC to start certain
operation.
A 74F74, D-type flip-flop, is used to start the
counting of the three trigger position counters and keep
them active.

CHAPTER 4
EXAMPLES OF OPERATION
4.1
An Example of Setting Trigger Condition
The trigger condition setting is critical for hardware
debugging.
This allows the user to see the timing
variation when the specified conditions occur.
The example presented here is to catch the interrupt
signal generated by a peripheral chip to 80186 CPU.
sec,
The system under test is a Z8530
Serial
Communication Controller, interfaced with 80186
microprocessor system.
An interrupt signal is expected
whenever the Z8530 transmitter buffer becomes empty.
The
interrupt signal will appear on 80186 INTl control line.
The procedures are as follows:
1.
Select the internal clock source.
2.
Select 50 HHz clock rate since the timing for
sec
is
several hundred nano-seconds.
3.
Hook the analyzer channel 0 clipper on INT line of
and ground clipper on
sec
sec
ground line, and hook the
other clippers on the signal lines that we want to
see, for example, channel 1 for
for
4.
sec
sec
CE line, channel 2
RD line.
Select the trigger word.
In this case, the trigger
word selected is all "don't care" except channel 0
with "0" since the INT generated by SCC is active low.
17
18
5.
Arbitrary select the trigger position at "255".
6.
Select "Capture" to start the acquisition.
7.
If there is any interrupt occurs, it will acquire
by the analyzer and store in the memory.
Otherwise,
the analyzer will walt for the trlqger.
8.
Select "Timing" to see the result in timing diagram
form.
9.
Save the result in a diskette if needed.
4.2
An example of using state list
In the previous example, after making sure there is
interrupt generated, we might want to see the interrupt
vector presented by the SCC.
This time the interrupt
acknowledge signal is using together with RD signal as
trigger condition.
1.
The procedure are as follows:
Hook the analyzer channel 3 clipper on INTACK line of
sec.
Hook channel 8 clipper on DO of
sec, channel
9
on Dl, channel 10 on D2, channel 11 on D3, channel 12
on D4, channel 13 on D5, channel 14 on D6, channel 15
on D7.
2.
Follow the setting of previous example.
3.
Change the trigger word as follows: "O" for channel 2
and channel 3, all other channels are "don't care".
The reason is that the interrupt vector from
be valid when both INTACK and RD are active.
4.
Select "capture" to start the acquisition.
5.
If the signals meet the trigger condition
sec will
19
requirements, they will be acquired by the analyzer
and stored in the memory.
Otherwise, the analyzer
will wait for the trlqger.
6.
Select "State list" (L) to see the interrupt vector at
the trigqer point in either binary or hexadec1Dal
form.
7.
Save the result in a diskette if needed.
4.3
An Example of Usinq Repeat Timinq Mode
The repeat timing mode is very useful when we want to
see the waveform continuously.
The example presented here is to see the refresh
timing of a dynamic RAM circuit.
4464s.
The dynamic RAMs used are
The refreshment of the dynamic RAM is done by RAS
without CAS siqnal and there should be 256 refresh cycles
within 4 mini-second.
These signals are generated by 80186
HCS lines and some interface circuits, the refresh signal
is controlled by the DMA controller inside 80186 chip.
By
accessing the dynamic RAM continuously, the changes of RAS,
CAS, WR, MUX, and other important siqnals can be displayed.
These are are done to see if the refresh signal generated
can fulfill the timinq requirements all the time.
The
procedure are as follows:
1.
Hook the analyzer channel 0 clipper on the RAS signal
line, and hook channel 1 clipper on the WR siqnal
line, and hook channel 2 clipper on the CAS signal
line, and hook channel 3 clipper on the HCS2 line
20
which is used to generate the refresh signal.
2.
Select the internal clock source.
3.
Select SO KHz clock rate.
4.
Select the trigger word as "0" for
HCS2 line, and
"don't care" for all other channels.
5.
Select the trigger position at 255.
6.
Select "capture" to start the acquisition.
7.
Select "Repeat" to see the changes continuously.
8.
With the waveform, we can see the RAS only signal and
determine if it can fulfill the timing requirement.
4.4
An Example of Using External Clock
Signals generated can be synchronized with a external
signal.
The external signal is used as external clock
source for the acquisition.
The example presented is to see the address generated
by 80186 CPU when a certain memory location is accessed.
The ALE signal generated by 80186 CPU will be used as
external clock.
1.
The procedure are as follows:
Hook the analyzer channel 0 through channel 15
clippers on the latched address lines AO through A15
correspondingly.

CONCLUSION
This report described the design of a SO MHz logic
analyzer based on an IBM PC.
be up to SO MHz.
The sampling clock rate can
The system is good for testing circuits
with operating speed up to 10 HHz since the sampling clock
rate is 4 to 5 times greater than the incoming data rate.
The system has the capability of displaying data in both
timing diagram and state list forms.
Also, it can
synchronize with the external clock.
The system can accept
up to 24 channels and have the capability of storing data
up to 1024 words.
The analyzer is easy to use since it
incorporates the convenience of inputting operations with
keyboard and displaying results on monitor with an IBM PC.
Also, on-screen menu is used to guide user to operate the
analyzer.
