Section 2: INSTALLATION AND CONNECTIONS

This section describes how to do the following:

install the application software onto the hard disk

configure the DAS 9200

configure the probe adapter

connect the DAS 9200 to the SUT (system under test)

INSTALLING SOFTWARE

Before installing the microcontroller 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 microcontroller 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.

4. Select Install Application in the Operation field of the menu.

Installation and Connections

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.

CONFIGURING THE PROBE ADAPTER

The Normal/Timing jumper (J1220) configures the probe adapter for either normal operation or to acquire timing data. It should be placed in the DISASM position to acquire state data, and in the TIMING position to acquire timing data. (When acquiring timing data, the multiplexers on the probe are held in “straight-through” mode; addresses are logged with address bit A0 logged on A0:0, A1 logged on A0:1, A2 on A0:2, and so on, regardless of what type of access is taking place.) Figure 2-2 shows the location of J1220 on the probe adapter.

Installation and Connections

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 microcontroller 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 microcontroller, 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 microcontroller 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.

Installation and Connections

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 microcontroller, causing the probe adapter to malfunction.

Please contact your IC manufacturer to verify that the microcontroller you are targeting conforms to the JEDEC specification.

For best performance and long probe life, exercise extreme care when connecting the probe to the microcontroller.

Section 3: SETTING UP SUPPORT SOFTWARE

This section provides information on preparing the support software for acquiring data. The section discusses the following:

load support software

channel groups and assignments

changes that affect the data display

clocking options

symbols

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 Am29205 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 29205 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 Am29205 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 microcontroller. The channel groups for the Am29205 microcontroller are the following:

ACCESS ADDRESS CONTROL DATA INTR MISC PRGRMIO

92DM927 Am29205 Instruction Manual Online Version

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 tables 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 92DM927 support software offers a customized clocking selection for the Am29205 microcontroller. This clocking choice (Custom) is the default selection whenever you select 29205 Software Support in the Configuration menu.

The 92DM927 support software provides two modes for acquiring Am29205 data: DRAM Refresh Cycles Included or DRAM Refresh Cycles Not Included. The default is DRAM Refresh Cycles Not Included. You can change the clocking mode by changing the DRAM Refresh Cycles option field in the Clock menu.

DRAM Refresh Cycle. A DRAM Refresh Cycle is defined as any RAS signal before a CAS signal (implicit) Refresh that is not in the background of another memory access.

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 Am29205 system prior to, during, and after attempting to integrate your software with the Am29205 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:

clocking

triggering

displaying data

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 29205_96 can be used to view Am29205 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 Am29205 system connections.

CLOCKING

To change the data sampling rate, use the Clock menu. The Normal/Timing jumper, J1220, on the probe adapter should be set

in the Timing position to acquire timing data. For more information on the Normal/Timing jumper, refer to Section 2.

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.

92DM927 Am29205 Instruction Manual Online Version

5-1

General Purpose Analysis

The Clock menu is shown in Figure 3-1. The default clocking mode is Custom when microcontroller 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 Am29205 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: 3 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 Am29205 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. The Normal/Timing jumper, J1220, on the probe adapter should be set in the Timing position to acquire timing data. For more information on the Normal/Timing jumper, refer to Section 2.

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 Am29205 microcontroller support, is available for you to use when displaying data in the Timing format. The 29205_96 file is installed on the DAS 9200 with the support software.

The 29205_96 Timing Format file places the Am29205 system clock first followed by the Address and Data groups displayed as bus forms containing bus values instead of as individual timing waveforms. These groups are followed by other important control signals. Figure 5-1 shows data displayed using the 29205_96 file.

To select the supplied Timing Format Definition file, follow these steps:

6. No bent or missing pins on the Am29205 microcontroller or on either of the probe adapter sockets.

Other Suggestions. If the previous suggestions do not fix the problem with acquiring data, try the following:

1. Reload the module setup; select 29205 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 Am29205 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 Am29205 system. Try performing hardware analysis with your DAS 9200 system to ensure that the Am29205 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 Am29205 system signals.

Appendix B: HOW DATA IS ACQUIRED

This appendix explains how the 92A96 Module acquires Am29205 signals using the 92DM927 probe adapter and software. This appendix also provides additional information on microcontroller signals accessible on or 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 Am29205 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 Am29205 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 Am29205 bus cycle, no matter how many clock cycles are contained in that cycle.

ROM, PIA, or DMA Access

ROM, PIA, and DMA accesses can be extended by the WAIT* signal and can be of different lengths depending on the WSx, IOWAITx, and DMAWAITx bits in the internal registers. Because of this, the CSM waits until the control signal disappears to identify the end of the cycle. Figure B-1 shows the strobe points and the master sample for ROM, PIA, and DMA accesses.

DRAM Refresh Cycles Excluded

DRAM Refresh cycles are not acquired or displayed.

DRAM Refresh Cycles Included

All bus cycles, including DRAM refresh cycles, are logged in.

ALTERNATE MICROCONTROLLER CONNECTIONS

You can connect to microcontroller signals that are not required by the support software so you can do more advanced timing analysis. These signals may or may not be accessible on the probe adapter board. The following paragraphs and tables list signals that are accessible on or are not 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.

Signals On the Probe Adapter

The probe adapter board contains pins for microcontroller signals that are not acquired by the 92DM927 software. You can connect extra podlets to these pins, because they can be useful for general purpose analysis. However, these signals are not defined in the Channel setup menu; you must enter the Channel setup menu and assign those signals to a new channel group.

Table B-1 shows the microcontroller signals available on the probe adapter’s square pin grid; the rest of the microcontroller signals on the grid are connected to the probe adapter. Refer to the PQFP100 Converter Chip Instructions included with this product for a pin number locator diagram.

PROBE ADAPTER DESCRIPTION

The probe adapter is a nonintrusive piece of hardware that allows the 92A96 to acquire data from an Am29205 microcontroller 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 Am29205 microcontroller. The probe adapter connects to the SUT. Signals from the Am29205 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 SUT (system under test).

The probe adapter accommodates the AMD Am29205 microcontroller in a 100-pin PQFP package.

Service Information

Configuring the Probe Adapter

The Normal/Timing jumper (J1220) should be placed in the DISASM position to acquire state data, and in the TIMING position to acquire timing data. (When acquiring timing data, the multiplexers on the probe are held in “straight-through” mode; addresses are logged with address bit A0 logged on A0:0, A1 logged on A0:1, A2 on A0:2, and so on, regardless of what type of access is taking place.)

Probe Adapter Circuit Description

The probe adapter uses a 74F373 to latch 8 bits of the RAS address during a DRAM access, and three 74F157As to demultiplex the DRAM (RAS and CAS) address onto the 92A96 address podlets. During any other access, the multiplexers are set to pass the signals straight through.

Two 16L8s funnel the control signals down into 8 Clocks/Quals and generate the latch enable signal (RAS_D*). They also latch the 19th and 21st bits of the RAS address, demultiplex the 23rd bit of the RAS address, generate the mux-select signal, and distinguish a refresh from a real access by latching the logical value of (CAS2* or CAS3*) when RASx goes low.

The probe adapter supports both page-mode and static-column DRAM access by latching the upper address (RAS) in hardware and logging these cycles with their proper addresses. The acquired data’s timestamp is the only indication, in a static column or page block mode, that the read was a single read or a group of reads.

Jumper J1220 on the probe adapter holds the multiplexer chips in “straight through” mode. This allows asynchronous clocking to capture the actual address regardless of the type of access.

The PDT jumper provides support for the PDT reset line; pin 1 is ground and pin 2 is the RESET* signal.

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.

Service Information

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.

2. If you are replacing a single podlet, orient the podlet connector marked GND towards the side of the podlet holder labeled GROUND.

3. Grasp the plastic pull tab on each side of the holder and gently spread the sides of the holder open just enough to clear the podlet.

4. Hold the podlet body with the other hand and place it in the

holder in the correct channel order. Do not grasp and turn the podlet cable.

ganging the podlets together starting with either channel 0 or channel 7. Orient the podlet channel marked GND towards the side of the podlet holder labeled GROUND.

C-15

Service Information

CAUTION

Avoid twisting the podlet cables between the interface housing and the podlet holder. To prevent damage to the podlets, keep the podlet cables parallel to each other when ganging them into the holder.

6. Hold the podlet body, turn the podlet body parallel to the sides of the holder, move it into the holder, and use your fingers to press it into place perpendicular to the sides of the holder. Be sure to gang the podlets in the correct channel order according to the channel label on the podlet holder and podlet color code, with all ground channels toward the Ground side of the holder. Do not place the podlet into the holder by grasping the podlet cable.

7. Continue placing the next two podlets, one at a time, in channel order, in the podlet holder. Orient all ground channels toward the Ground side of the holder.

8. The fourth podlet should be either channel 0 or 7, whichever one is not already placed in the holder. Place this podlet in the other end of the podlet holder and orient the ground channel correctly.

9. Continue placing the next two podlets, one at a time, in channel order, in the podlet holder. Continue orienting the ground channels correctly.

CAUTION

Excessive pulling on the sides can break the podlet holder. Spread the holder open only wide enough to clear the podlet.

10. Grasp the plastic pull tab on each side of the holder and gently spread the sides of the holder open just enough to clear a podlet.

11. Place the last pair of podlets (channels 3 and 4) in the podlet holder in proper channel order, orienting the ground channels to the Ground side of the holder.

REMOVING AND REPLACING SOCKETS

C-16

The probe adapter board contains sockets designed to protect the probe adapter and to make it easy to insert and remove the microcontroller. The socket on top of the probe adapter board is soldered and cannot be removed. The protective socket on the bottom of the probe adapter board can be removed.
