PGA Probe Adapter

The channel and clock probes shown in this chapter are for a 102-channel module. Your probes will look different if you are using a 96-channel module.

The general requirements and restrictions of microprocessor supports in the information on basic operations shows the vertical dimensions of a channel or clock probe connected to square pins on a circuit board.

To connect the logic analyzer to a SUT using a PGA probe adapter, follow these steps:

1. Turn off power to your SUT. It is not necessary to turn off power to the logic

analyzer.

CAUTION. Static discharge can damage the microprocessor, the probe adapter, the probes, or the module. To prevent static damage, handle all of the above only in a static-free environment.

Always wear a grounding wrist strap or similar device while handling the microprocessor and probe adapter.

Getting Started

2. To discharge your stored static electricity, touch the ground connector located

on the back of the logic analyzer. 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 1–1. This prevents the circuit board from flexing and the socket pins from bending.

4. Remove the microprocessor from your SUT.

5. Line up the pin A1 indicator on the probe adapter board with the pin A1

indicator on the microprocessor.

CAUTION. Failure to correctly place the microprocessor into the probe adapter might permanently damage the microprocessor once power is applied.

To connect the logic analyzer to a SUT using a PLCC probe adapter, follow these steps:

1. Turn off power to your SUT. It is not necessary to turn off the logic analyzer.

CAUTION. Static discharge can damage the microprocessor, the probe adapter, the probes, or the module. To prevent static damage, handle all of the above only in a static-free environment.

Always wear a grounding wrist strap or similar device while handling the microprocessor and probe adapter.

2. To discharge your stored static electricity, touch the ground connector located

on the back of the logic analyzer. 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 1–4. This prevents the circuit board from flexing.

Operating Basics

Setting Up the Support

This section provides information on how to set up the support. Information covers the following topics:

H Channel group definitions H Clocking options H Symbol table files

Remember that the information in this section is specific to the operations and functions of the TMS 103 80286 support on any Tektronix logic analyzer for which it can be purchased. Information on basic operations describes general tasks and functions.

Before you acquire and disassemble data, you need to load the support and specify setups for clocking, and triggering as described in the information on basic operations. The support provides default values for each of these setups, but you can change them as needed.

Channel Group Definitions

Clocking Options

The software automatically defines channel groups for the support. The channel groups for the 80286 support are Address, Data, Control, Intr, Copr and Misc. If you want to know which signal is in which group, refer to the channel assignment tables beginning on page 3–5.

The TMS 103 support offers a microprocessor-specific clocking mode for the 80286 microprocessor. This clocking mode is the default selection whenever you select the 286 support.

(For the 102-channel module, from the File menu, select Load Support Package, and 286. For the 96-channel module, select 286 Support in the Configuration menu.)

The clocking options for the TMS 103 support is DMA Cycles. A description of how cycles are sampled by the module using the support and

probe adapter is found in the Specifications chapter.

A DMA cycle is defined as the 80286 giving up the bus to an alternate device (a DMA device or another microprocessor). All bus cycles, including visible DMA cycles, are acquired when you select Included.

The TMS 103 support supplies one symbol table file. The 286_Ctrl file replaces specific Control channel group values with symbolic values when Symbolic is the radix for the channel group.

Table 2–1 shows the name, bit pattern, and meaning for the symbols in the file 286_Ctrl, the Control group symbol table.

Probe Adapter Description

The probe adapter is a nonintrusive piece of hardware that allows the acquisition module to acquire data from a 80286 microprocessor in its own operating environment with little affect, if any, on that system. Information on basic operations contains a figure showing the logic analyzer connected to a typical probe adapter. Refer to that figure while reading the following description.

Configuration

Specifications

The probe adapter consists of a circuit board and a socket for a 80286 microprocessor. The probe adapter connects to the microprocessor in the SUT. Signals from the microprocessor-based system flow from the probe adapter to the channel groups and through the probe signal leads to the module.

All circuitry on the probe adapter is powered from the SUT. The PGA probe adapter accommodates the 80286 microprocessor in a 68-pin

PGA package. The PLCC probe adapter accommodates the 80286 microprocessor in a 68-pin PLCC package.

The probe adapter does not require any configuration.

These specifications are for a probe adapter connected to a compatible Tektronix logic analyzer, and the SUT. Table 3–1 shows the electrical requirements the SUT must produce for the support to acquire correct data.

These channels are used only to clock in data; they are not acquired or displayed. To acquire data from any of the signals shown in Table 3–10, you must connect another channel probe to the signal, called double probing. An equals sign (=) following a signal name indicates that it is already double probed.

How Data is Acquired

80286 Clocking

This part of this chapter explains how the module acquires 80286 signals using the TMS 103 support and probe adapter. This part also provides additional information on microprocessor signals accessible on or not accessible on the probe adapter, and on extra acquisition channels available for you to use for additional connections

A special clocking program is loaded to the module every time you select the microprocessor support. This special clocking is called Custom for the 102-channel module or 96-channel module.

With this clocking, the module logs in signals from multiple groups of channels at different times when they are valid on the 80286 bus. The module then sends all the logged-in signals to the trigger machine and to the acquisition memory of the module for storage.

TMS 103 80286 Microprocessor Support Instruction Manual

Specifications

In Custom clocking for the 102-channel module or the 96-channel module, the module clocking state machine (CSM) generates one master sample for each 80286 bus cycle, no matter how many clock cycles are contained in the bus cycle.

Figure 3–3 shows the sample points and the master sample point.

TMS 103 80286 Microprocessor Support Instruction Manual

Specifications

Clocking Options

The clocking algorithm for the 80286 support is DMA Cycles.

DMA Cycles Excluded. Whenever the HLDA signal is high, no bus cycles are logged in. If either S1~ or S0~ become asserted while HLDA is high, a bus cycle has started and will continue until READY~ becomes asserted. Only bus cycles driven by the 80286 microprocessor (HLDA low) will be logged in.

DMA Cycles Included. All bus cycles, including DMA cycles, are logged in. When the HLDA signal is high, the 80286 microprocessor has given up the bus

to an alternate device. The design of the 80286 system affects what data will be logged in. The support only samples the data at the pins of the 80286 microprocessor. To properly log in bus activity, any buffers between the 80286 microprocessor and the alternate bus master must be enabled and pointing at the 80286 microprocessor.

There are three possible 80286 system designs and clocking interactions when an alternate bus master has control of the bus. The three different possibilities are listed below (in each case, the HLDA signal is logged in as a high level):

H If the alternate bus master drives the same control lines as the 80286

microprocessor, and the 80286 microprocessor “sees” these signals, the bus activity is logged in like normal bus cycles except that the HLDA signal is high.

H If HLDA and S0~ or S1~ become active, then the current bus cycle will be

logged in as a DMA cycle.

H If HLDA becomes active and then inactive without either S0~ or S1~

becoming active, then the bus cycle will be logged in with the current bus cycles Address and Controls and the previous bus cycles Data.

When logging in DMA cycles, the data bus and control signals are logged in on the falling clock edge.

Alternate Microprocessor Connections

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

For a list of signals required or not required for disassembly, refer to the channel assignment tables beginning on page 3–5.

Extra Channels

Table 3–11 lists extra channels that are left after you have connected all the channels used by the support. You can use these extra channels to make alternate SUT connections. You can also disconnect channels not required by the support to make alternate connections. The channel assignment tables in this chapter indicate channels not required by the support for disassembly.

WARNING

The following servicing instructions are for use only by qualified personnel. To avoid injury, do not perform any servicing other than that stated in the operating instructions unless you are qualified to do so. Refer to all Safety Summaries before performing any service.

Maintenance

This section contains information on the probe adapter circuit description.

Probe Adapter Circuit Description

The TMS 103 probe adapter uses a 20R6 PAL (U1000) configured to act as a negative-edge triggered D flip-flop. This circuitry acts to latch the necessary control lines, ensuring the state of READY~, HLDA, M/IO~, and COD/INTA~. READY~ is the user-generated signal that ends the current bus cycle and is latched to meet the minimum setup time as a qualifier. HLDA is also latched to meet the minimum setup time as a qualifier. M/IO~ and COD/INTA~ are both latched to avoid uncertainty in the CPU idle cycle.

The clocking state machine uses the falling edge of CLK to determine when to log the necessary signals.
