INSTALLING SOFTWARE
Before installing the digital signal processor application software, you should be aware that there are three different versions of DAS 9200 system software: the 9201T version, the 92XTerm, and the 9202XT version. The 9201T version allows you to operate the DAS 9200 from a 9201T terminal. The 92XTerm version allows you to operate the DAS 9200 in an X window on a workstation. The 9202XT version allows you to operate the DAS 9200 in an X window from a 9202XT terminal.
NOTE
To use the digital signal processor support package, you must install application software that is compatible with your DAS 9200 mainframe configuration and system software.
If you have any two types of DAS 9200 system software (9201T, 92XTerm, 9202XT), and you switch between the two, you must install compatible application software on each system.
If you try to install application software onto an incompatible system or terminal using DAS 9200 System Software Release 3, V1.1 or greater, an error message displays.
If you try to install application software onto an incompatible system or terminal using DAS 9200 System Software Release 3, V1.0 or lower, the system will install the software but it will not operate properly when you try to use it.
Install the application software onto the DAS 9200 as follows:
1. Power on the DAS 9200 mainframe.
2. Insert the appropriate disk into the DAS 9200’s floppy drive.
3. Press the Select Menu key, and select the Disk Services menu.

Installation and Connections
4. Select Install Application in the Operation field of the menu.
5. Press F8: EXECUTE OPERATION, and follow the on-screen prompts.
NOTE
After each install and load operation, a message appears on the screen informing you the operation succeeded or failed. If the message tells you the operation failed, you may need to remove applications or files from the hard disk and try installing or loading again. If the operation fails again, refer to Appendix A: Error Messages and
Acquisition Problems.
If there is inadequate disk free space available on the hard disk, you must use the Remove Application or Delete File function of the Disk Services menu to free up enough disk space to install the support software. The approximate space required to install the software is listed on the label of the floppy disk.
CONFIGURING THE DAS 9200
When there are two or three 92A96 Modules in adjacent slots, they are automatically formed into a variable-width module by the system software at power up. If you need to use one 92A96 Module from a variable-width module, you must reconfigure the DAS 9200 prior to selecting software support in the 92A96 Configuration menu. Refer to the discussion of the System Configuration menu in the DAS 9200 System User Manual for details on how to reconfigure variable-width modules.
Refer to your module user manual for additional information about connecting probe cables, and positioning and installing 92A96 Modules.
In a system with many modules, it is easier to identify which modules are connected to the probe adapter if slot number labels are applied to the 92A96 probe interface housings and DAS 9200 mainframe. Figure 2-1 shows where to apply slot number labels.

Figure 2-1. Applying slot number labels.
CONFIGURING THE PROBE ADAPTER
There are two jumpers on the probe adapter. One is set to match the Read/Write signal convention of your DSP3210 system. The second is used to configure the probe adapter to acquire data when the BLMN signal is asserted or to acquire data when the PBD signal is asserted.
Read/Write Signal Convention Jumper
When J4010 is in the 1-2 position, the RW signal behaves like an R/W* signal in a Motorola 680x0 microprocessor. When J4010 is in the 2-3 position, the RW signal behaves like a W/R* signal in an Intel i386 microprocessor.
Table 2-1 shows the jumper positions for J4010. Figure 2-2 shows the location of the jumper on the probe adapter.

BLMN or PBD Signal Selection Jumper
When J4000 is in the 1-2 position, the BLMN signal is selected. When the signal is asserted, the signal indicates that the DSP3210 is starting a quad-word block move operation. When J4000 is in the 2-3 position, the PBD signal is selected. When asserted, it indicates that the current external memory access is not on the same page as the previous external memory access.
Table 2-2 shows the jumper positions for J4000. Figure 2-2 shows the location of the jumper on the probe adapter.

Clock Compensation Resistor Selection
To ensure the integrity of the acquired data, either R1140 or R1240 is inserted on the probe adapter board during manufacturing. The resistors are both 0 ohm (zero) and actually function as wires straps.
Figure 2-2 shows the location of the resistor on the probe adapter. Only one of the two resistors is connected to the board. Appendix C
describes how to select one of the two resistor positions.
CONNECTING TO THE SYSTEM UNDER TEST
Before you connect to the SUT, you must connect the standard probes to the 92A96 Module card. Your SUT must also have a minimum amount of clear space surrounding the digital signal processor to accommodate the probe adapter. Refer to Appendix C: Service Information for the required clearances.
To connect the probe adapter to the SUT, do the following:
1. Turn off power to your SUT. It is not necessary to turn off the DAS 9200.
CAUTION
Static discharge can damage the digital signal processor, probe adapter, podlets, or the 92A96 Module. To prevent static damage, handle all the above only in a static-free environment.
Always wear a grounding wrist strap, or a similar device, while handling the digital signal processor and probe adapter.
2. To discharge your stored static electricity, touch the ground jack located on the back of the DAS 9200. Then, touch any of the ground pins of the probe adapter to discharge stored static electricity from the probe adapter.
3. Place the probe adapter onto the antistatic shipping foam to support the probe as shown in Figure 2-3. This prevents the circuit board from flexing.
4. Connect the clock and 8-channel probes to the probe adapter as shown in Figure 2-3. Match the channel groups and numbers on the interface housing to the corresponding pins on the probe adapter.

8-CHANNEL PROBE
Hold the 8-Channel Probes by the podlet holder when con­necting them to the probe adapter. Do not hold them by the cables or necks of the podlets.
Figure 2-3. Connecting the podlets to a typical PQFP probe adapter.
CAUTION
This JEDEC PQFP (Plastic Quad Flat Pack) probe adapter is equipped with a clip that has been designed for tight tolerances.
The clip supports only Plastic Quad Flat Pack devices that conform to the JEDEC M0-069 October 1990 specification. Attaching the clip to a device that does not conform to this JEDEC standard can easily damage the clip’s connection pins and/or the digital signal processor, causing the probe adapter to malfunction.
Please contact your IC manufacturer to verify that the digital signal processor you are targeting conforms to the JEDEC specification.
For best performance and long probe life, exercise extreme care when connecting the probe to the digital signal processor.

triggering
Before you acquire and display data, you need to load support software and specify setups for clocking, triggering, and using symbols. The software provides default values for each of these setup controls, but you can change them as needed.
LOADING SUPPORT SOFTWARE
To load the DSP3210 support software, follow these steps:
1. Press the Menu Select key, select the appropriate 92A96 Module, select its Configuration menu, and press Return.
2. Select 3210 in the Software Support field.
3. Press F8: EXECUTE OPERATION.
When you load the support software, the Channel, Clock, and Trigger menus are automatically set up to acquire data from your DSP3210 system. You can change the setups in the Clock and Trigger menus as needed. Refer to Channel Groups and Assignments for information on what can be changed in the Channel menu.
CHANNEL GROUPS AND ASSIGNMENTS
The support software automatically defines the channel groups for the digital signal processor. The channel groups for the DSP3210 digital signal processor are the following:
ADDRESS DATA MEM_SEL MISC2 CONTROL INTR MISC1 SERIAL
92DM926 DSP3210 Instruction Manual

Setting Up Support Software
These channel groups cannot be changed nor can the channels be reused in another group; however, you can define and display additional groups. If you want to know which signal is in which group, refer to the channel assignment table in Appendix C: Service Information. Channel assignments are also shown in the 92A96 Channel setup menu.
CHANGES THAT AFFECT THE DATA DISPLAY
You can change part of the default setups for the 92A96 Module. However, keep in mind that if you change the threshold voltage or display polarity, the displayed data will be affected.
CUSTOM CLOCKING
You can use the Clock menu to set clocking choices to control data sampling. The 92DM926 support software offers a customized clocking selection for the DSP3210 digital signal processor. This clocking choice (Custom) is the default selection whenever you select 3210 Software Support in the Configuration menu.
The 92DM926 support software provides two modes for acquiring DSP3210 data: DMA Cycles Excluded or DMA Cycles Included. The default is DMA Cycles Excluded. You can change the clocking mode by changing the DMA Cycles option field in the Clock menu.
Figure 3-1 shows the Clock menu. A description of how cycles are sampled by the support software, probe adapter, and 92A96 is found in Appendix B: How Data is Acquired.

Section 5: GENERAL PURPOSE ANALYSIS
You may need to perform general purpose (timing) analysis on your DSP3210 system prior to, during, and after attempting to integrate your software with the DSP3210 system hardware. When performing hardware analysis, you will want to use the data acquisition module to acquire data with a finer resolution. When more data samples are taken in a given period of time, the resolution in the Timing display increases, letting you see signal activity that would otherwise go undetected.
This section provides information on the following:
S
clocking
S
triggering
S
displaying data
S
supplied Timing Format Definition file
To acquire and display timing data, you need to change the clocking selection and trigger program, acquire data, and view it in the Timing menu. A predefined Timing Format Definition overlay file called 3210_96 can be used to view DSP3210 timing data. A description of these files and how to use them can be found later in this section.
There often is a need to view data in a split screen display with state data in one half and timing data in the other. Do not disconnect any of the 92A96 probe cables or interface housings if you are analyzing data in this manner. Instead, use the extra channels available from the 92A96 Module to make other DSP3210 system connections. Refer to the channel assignment tables in Appendix C to see which channels are not required by the support software. You can disconnect these channels to make other DSP3210 system connections.
CLOCKING
To change the data sampling rate, use the Clock menu. When using the 92A96 Module for timing analysis, you will want to
use the Internal or External clocking modes. The Internal clock selection can sample data up to 100 MHz, which has a 10 ns resolution between samples. The External clock selection samples data on every active clock edge on the 92A96 clock inputs up to 100 MHz.
92DM926 DSP3210 Instruction Manual
5-1
General Purpose Analysis
The Clock menu is shown in Figure 3-1. The default clocking mode is Custom when digital signal processor support is used; you will need to change it to either Internal or External. Your 92A96 Module User Manual contains an in-depth description of Internal and External clocking.
Custom Clocking
Custom clocking only stores one data sample for each bus transaction, which can take one or more clock cycles. Custom clocking also time-aligns certain signals that otherwise would be skewed relative to the current bus transaction. This clocking selection is generally unproductive for timing analysis. Refer to Appendix B for a more in-depth description of how Custom clocking is used with the probe adapter to acquire data.
Internal Clocking
When you select Internal as the clocking mode, the 92A96 Module stores one data sample as often as every 10 ns (100 MHz). This clocking selection is commonly referred to as asynchronous.
Two typical uses of Internal clocking might be to verify that all the DSP3210 signals are transitioning as expected or to measure timing relationship between signal transitions.
It is possible to acquire asynchronous data at rates of 200 MHz and 400 MHz. The faster the 92A96 Module acquires data, the fewer channels it can acquire data on. A single 92A96 Module can acquire data on 24 channels at 400 MHz or 2.5 ns resolution. Refer to your 92A96 Module User Manual for information on sampling data at speeds faster than 100 MHz.
External Clocking
When you select External as the clocking mode, the 92A96 Module acquires and stores data based on the clock channel up to 100 MHz. This clocking selection is commonly referred to as synchronous.
By selecting the rising edge of CLK: 2 on the acquisition module as the clock channel, and turning off the remaining three clocks, the module will sample data on every rising edge of the clock. No data is acquired on the falling clock edge unless you select both edges.

You can also use the other three clock channels as qualifiers or clocks to further modify the clocking in of information from your DSP3210 system.

TRIGGERING
All the Trigger menu selections available for use with the 92A96 Module are still available for use with timing analysis. Refer to your module user manual for a list and description of the selections.
ACQUIRING DATA
You can acquire data as described in the Acquiring Data description in Section 4.
DISPLAYING DATA
General purpose analysis requires that you view data in either the State or Timing menus. The following discussion describes these menus.
Timing Menu
In the Timing menu, every channel is shown as a waveform, and groups of channels are shown as bus forms.
A predefined Timing Format Definition overlay file, part of the DSP3210 digital signal processor support, is available for you to use when displaying data in the Timing format. The 3210_96 file is installed on the DAS 9200 with the support software.
The 3210_96 Timing Format file places the Address and Data groups first and displays them as bus forms containing bus values instead of as individual timing waveforms. These groups are followed by the DSP3210 system clock and other important control signals. Figure 5-1 shows data displayed using the 3210_96 file.
To select the supplied Timing Format Definition file, follow these steps:
1. Select the Timing menu and press F5: DEFINE FORMAT.
2. Press F5: RESTORE FORMAT.
3. Select 3210_96, and press the Return key. A message tells you the format file is selected.
4. Press F8: EXIT & SAVE to return to the Timing menu.
Refer to the channel assignment tables in Appendix C for the lists of individual channels and their DSP3210 signal names.

State Menu
In the State menu, all channel group values are shown based on the selected radix in the Channel menu or the State Format Definition overlay. This menu shows the bus cycles with addresses, data, and other group values if selected.
If you want to display other channel groups (such as Misc1 or Misc2), access the State Format Definition overlay and change the radix for the group from Off to Hex, Bin, or Oct. This overlay also allows you to add the Timestamp group (and change the radix) to the data display.

SEARCHING THROUGH DATA
To search through data, you can use either the Timing Search Definition overlay or the State Search Definition overlay. You can use these overlays and search through data as described in your 92A96 Module User Manual.
Before performing a search in the Timing menu, be sure to check the State Format Definition overlay and make sure the channels on which you want to conduct the search will be displayed (radix is not Off). Channels in the Timing menu cannot be searched on unless they can also be displayed in the State menu.

Other Suggestions. If the previous suggestions do not fix the problem with acquiring data, try the following:
1. Reload the module setup; select 3210 Support in the 92A96 Configuration menu to restore the DAS 9200 to a known state.
2. Possible AC and DC loading problems may be remedied by removing one or both of the protective sockets from the probe adapter. These sockets may add enough additional inductance to your DSP3210 system to affect it. Refer to Appendix C for a description to remove sockets from the probe adapter.
If the DAS 9200 still is not acquiring data after trying these solutions, there may be a problem with your DSP3210 system. Try performing hardware analysis with your DAS 9200 system to ensure that the DSP3210 signals are valid at the time the probe adapter samples them.
Refer to Section 5: General Purpose Analysis for information on data sampling rates using either the Internal or External clocking selections in the Clock menu. Also refer to Appendix B: How Data is Acquired to see when the support software, probe adapter, and 92A96 Module sample the various DSP3210 system signals.

Appendix B: HOW DATA IS ACQUIRED
This appendix explains how the 92A96 Module acquires DSP3210 signals using the 92DM926 probe adapter and software. This appendix also provides additional information on digital signal processor signals not accessible on the probe adapter, and on extra 92A96 channels available for you to use for additional connections.
92A96 CUSTOM CLOCKING
A special clocking program (called Custom) is loaded to the 92A96 Module every time the DSP3210 Software Support is selected in the Configuration menu. With Custom clocking, the module logs in signals from multiple groups of channels at different times when they are valid on the DSP3210 bus. The module then sends all the logged-in signals to the trigger machine and to the acquisition memory of the module for storage.
In Custom clocking, the module’s clocking state machine (CSM) generates one master sample for each DSP3210 bus cycle, no matter how many clock cycles are contained in that cycle.
Figure B-1 shows the sample points and the master sample.

The 92A96 clocking algorithm for the DSP3210 digital signal processor has two variations: DMA Cycles Excluded, and DMA Cycles Included.
The BGN* signal must meet setup and hold times on every falling edge of CKI for correct data display.
DMA Cycles Excluded
The SUT requires that the BGN* value be held until SRDYN* is asserted.
If BGN* is inactive at the first falling clock edge after the cycle starts (when CSN* is active), then the current bus cycle is a DMA cycle. When the DMA Cycles Excluded clocking option is selected, DMA cycles are not logged. That is, the logic analyzer has no record that DMA cycles occurred.
DMA Cycles Included
Signals recognized as DMA cycles are logged in and labeled as DMA cycles.
A DMA cycle occurs when BGN* is inactive on the first falling edge of CKI after the cycle starts and CSN* is asserted. CSN* must remain asserted for the duration of the DMA cycle.
ALTERNATE DIGITAL SIGNAL PROCESSOR CONNECTIONS
You can connect to digital signal processor signals that are not required by the support software so you can do more advanced timing analysis. However, these signals are not be accessible on the probe adapter board.
For a list of signals required or not required by the support software, refer to the channel assignment tables in Appendix C.

PROBE ADAPTER DESCRIPTION
The probe adapter is a nonintrusive piece of hardware that allows the 92A96 to acquire data from a DSP3210 digital signal processor in its own operating environment with little affect, if any, on that system. Refer to Figure C-1 while reading the following discussion.
C-2
PROBE ADAPTER
Figure C-1. Overview of the standard probe and probe adapter.
The probe adapter consists of a circuit board and a socket for the DSP3210 digital signal processor. The probe adapter connects to the SUT. Signals from the DSP3210 system flow from the probe adapter to the podlet groups. The signals flow through the probe signal leads to the 92A96 Module.
All circuitry on the probe adapter is powered from the system under test.
The probe adapter accommodates the AT&T DSP3210 digital signal processor in a 132-pin PQFP package.

Configuring the Probe Adapter
There are two jumpers on the probe adapter. One is set to match the Read/Write signal convention of your DSP3210 system. The second is used to configure the probe adapter to acquire data when the BLMN signal is asserted or to acquire data when the PBD signal is asserted.
Read/Write Signal Convention Jumper. When J4010 is in the 1-2
position, the RW signal behaves like an R/W* signal in a Motorola 680x0 microprocessor. When J4010 is in the 2-3 position, the RW signal behaves like a W/R* signal in an Intel i386 microprocessor.
Table C-1 shows the jumper positions for J4010. Figure C-2 shows the location of the jumper on the probe adapter.

BLMN or PBD Signal Selection Jumper. When J4000 is in the 1-2
position, the BLMN signal is selected. When the signal is asserted, the signal indicates that the DSP3210 is starting a quad-word block move operation. When J4000 is in the 2-3 position, the PBD signal is selected. When asserted, it indicates that the current external memory access is not on the same page as the previous external memory access.

Clock Compensation Resistor Selection
To ensure the integrity of the acquired data, either R1140 or R1240 is inserted on the probe adapter board during manufacturing. The resistors are both 0 ohm (zero) and actually function as wires straps.
Figure C-2 shows the location of the resistor on the probe adapter. Only one of the two resistors is connected to the board. Due to the fast
fall time of the on-board part (74FR244, tf<2.0 ns) the selection procedures should be performed with an input of comparable edge speed. To obtain a comparable edge speed, use a 4 MHz oscillator and buffer the output of the oscillator through a 74FR244 before injecting the signal into the probe adapter.
To perform the procedure, you will need a 350 MHz oscilloscope, a pair of probes with bandwidth >350 MHz, and IC clips.
C-4
92DM926 DSP3210 Instruction Manual
Service Information
It is necessary to compensate for the skew between the two probes. To compensate for the skew, perform the following steps:
1. Set the A and B TIME/DIV to 1 ns.
2. Set CH1 and CH@ VOLTS/DIV to .5 V.
3. Set the trigger slope to –.
NOTE
Only falling edges are important in this procedure.
4. Set to trigger on Chan 2.
5. Put GND lead of Chan 2 probe on A1:7 GND.
6. Put GND lead of Chan 1 probe on C1/AUX:0 GND.
7. Connect both probe tips to CK:0 using IC clips.
8. Establish an x-y coordinate system for time difference measurements using an oscilloscope.
9. Measure the time difference (dt) of the two falling edges (@1.5V).
±dt = time Chan 2 probe – time Chan 1 probe
10. Take Chan 2 probe and clip it onto U1240, pin 11.
11. Attach an A96 CLK podlet to CK:0 and an A96 data podlet to C2:7.
12. Measure the time difference (tg) between the two falling edges (@1.5V).
tg = time Chan 1 probe – time Chan 2 probe (Result is always positive)
13. Solve for the actual propagation delay (tpd) with the probe’s skew accounted for.
tpd = tg + (±dt)
14. If tpd <3.0 ns, then leave the R1240 in its current position. Otherwise, remove R1240 and connect R1140.

Service Information
CARE AND MAINTENANCE
The probe adapter does not require scheduled or periodic maintenance. To maintain good electrical contact, keep the probe adapter free of dirt, dust, and contaminants. Also, ensure that any electrically conductive contaminants are removed.
Dirt and dust can usually be removed with a soft brush. For more extensive cleaning, use only a damp cloth. Abrasive cleaners and organic solvents should never be used.
CAUTION
The semiconductor devices contained on the probe adapter are susceptible to static-discharge damage. To prevent damage, service the probe adapter only in a static-free environment.
If the probe adapter is connected to your system, grasp the ground lug on the back of the DAS 9200 mainframe to discharge your stored static electricity. If the probe adapter is not connected, touch any of the ground pins (row of square pins closest to the edge of the probe adapter circuit board labeled GND) to discharge stored static electricity from the probe adapter.
Always wear a grounding wrist strap, or similar device, while servicing the instrument.
Exercise care when soldering on a multilayer circuit board. Excessive heat can damage the through-hole plating or lift a run or pad and damage the board beyond repair. Do not apply heat for longer than three seconds. Do not apply heat consecutively to adjacent leads. Allow a moment for the board to cool between each operation.
If you must replace an electrical component on a circuit board, exercise extreme caution while desoldering or soldering the new component. Use a pencil-type soldering iron of less than 18 watts and an approved desoldering tool. Ensure that the replacement is an equivalent part by comparing the description as listed in the replaceable parts list.
