Getting Started

PGA Probe Adapter

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 processor 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 processor 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 1–1. This prevents the circuit board from flexing and the

socket pins from bending.

4. Remove the processor from your SUT.

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

indicator on the processor.

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 702 TMS320C3X 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 TMS320C3X support are Address, Data, and Control. If you want to know which signal is in which group, refer to the channel assignment tables beginning on page 3–6.

The TMS 702 support offers a digital signal processor-specific clocking mode for the TMS320C3X processor. This clocking mode is the default selection whenever you load the TMS320C3X support.

A description of how cycles are sampled by the module using the support and probe adapter is found in the Specifications chapter.

Disassembly will not be correct with the Internal or External clocking modes. Information on basic operations describes how to use these clock selections for general purpose analysis.

The clocking options for the TMS 702 support are: Wait State Mode, Number of SW Wait, and Alternate Bus Master Cycles.

TMS 702 TMS320C3X Digital Signal Processor Support Instruction Manual

2–1

Setting Up the Support

Wait State Mode

The Wait State Mode field contains four selections that correspond to the

particular wait state mode you are using. The selections are Hardware Only, Software Only, HW or SW, and HW and SW.

Hardware Only. This wait state depends only on the status of the external RDY~ line. The software wait state (SW Waits) are ignored.

Software Only . This wait state depends only on the number of SW Waits programmed in the Num of SW Wait field. The status of the external RDY~ line is ignored.

HW or SW. This wait state depends on either the status of the external RDY~ line, or the number of SW Waits selected in the Num of SW Wait field, whichever occurs earlier.

HW and SW. This wait state depends on both the status of the external RDY~ line and the number of SW Waits selected in the Num of SW Wait field, whichever occurs earlier. HW and SW is the default setting.

The TMS320C3X digital signal processors occasionally generate redundant read or prefetch cycles when there is a contention for the internal pipeline resources or external memory. The disassembly software identifies these redundant cycles and flags them as “PIPELINE/MEMORY CONFLICT” cycles. Incorrect setting of the “Wait State Mode” or the “Num of SW Wait” states fields can cause incorrect disassembly.

Num of SW Wait

Alternate Bus Master

(ABM) Cycles

2–2

This field provides the number of SW Waits programed discussed under Wait State Mode. This selection allows you to program the support to acquire correct

bus data when software-programmed wait-states are used. You enter the number of wait states that the support is to insert in external cycles for the bus you are monitoring. You can enter a value from zero to seven which will be used by the Clocking State Machine (CSM) to track the completion of the bus cycle precisely as the processor does. The default setting is zero (none). If the Wait State Mode selected is HW Only, then the setting of this value does not matter.

The TMS 702 support has a select field with the label ABM Cycles. This field has two selections, Excluded and Included.

Excluded. Alternate Bus Master (ABM) Cycles are not acquired or displayed. Alternate Bus Master Cycles Excluded, is the default selection.

Included. All cycles are acquired.

Triggering on the

Expansion Address Bus

The TMS320C3X expansion bus is 13-bits wide. The TMS320C3X probe adapter ties the remaining most significant bits to ground. Therefore, when entering values for the expansion address bus in the trigger menus, you must enter those remaining bits as zeros. The disassembler synthesizes the upper bits to match the memory map of the TMS320C3X data book.

You must also indicate either the MSTRB~ or the IOSTRB~ in the Control section of the trigger menus. A convenient method would be to enter the symbols provided by the TMS320C3X support.

Marking Cycles

The disassembler has a Mark Opcode function that allows you to change the interpretation of a cycle type. Using this function, you can select a cycle and change it to one of the following cycle types:

H Opcode – the first word of an instruction H Flush – an opcode or extension that is fetched but not executed H Read – marks a memory reference read as data H Undo Marks – Removes all marks from the current sequence

You can also use the Mark Opcode function to specify the default segment size mode (16-bit or 32-bit) for the cycle. The segment size selection changes the cycle the cursor is on and the remaining cycles to the end of memory or to the next mark.

Information on basic operations contains more details on marking cycles.

Viewing an Example of Disassembled Data

A demonstration system file (or demonstration reference memory) is provided so you can see an example of how your TMS320C3X digital signal processor bus cycles and instruction mnemonics look when they are disassembled. Viewing the system file is not a requirement for preparing the module for use and you can view it without connecting the logic analyzer to your SUT.

Probe Adapter Description

The probe adapter is nonintrusive hardware that allows the logic analyzer to acquire data from a digital signal processor in its own operating environment with little effect, 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

The probe adapter consists of a circuit board and a socket for a TMS320C3X processor. The probe adapter connects to the processor in the SUT. Signals from the TMS320C3X-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 probe adapter accommodates the Texas Instruments TMS320C3X digital

signal processor in a 181-pin PGA package, and in the 132-pin PQFP package.

Place the Disassembly and Timing jumper in the D position to acquire disassembled data, and in the T position to acquire timing data. Table 3–1 shows how to position this jumper depending on the type of clocking you are using, and the type of window you want to view.

Channel Assignments

Channel assignments shown in Table 3–5 through Table 3–14 use the following conventions:

H All signals are required by the support unless indicated otherwise. H Channels are shown starting with the most significant bit (MSB) descending

to the least significant bit (LSB).

H Channel group assignments are for all modules unless otherwise noted. H An tilde (~) following a signal name indicates that the signal is active low. H An equals sign (=) following a signal name indicates that it is double probed. H If there are two modules (such as used to form 96-channels), the module in

the higher-numbered slot is referred to as the HI module and the module in the lower-numbered slot is referred to as the LO module.

Table 3–5 shows the probe section and channel assignments for the Primary bus Address group and the TMS320C3X signal to which each channel connects. By default, this channel group is displayed in hexadecimal.

How Data is Acquired

Specifications

This part of this chapter explains how the module acquires digital signal processor signals using the TMS 702 software and probe adapter. This part also provides additional information on digital signal processor signals accessible on or not accessible on the probe adapter, and on extra probe channels available for you to use for additional connections.

Custom Clocking

A special clocking program is loaded to the module every time you load the TMS320C3X support. This special clocking is called Custom.

With Custom clocking, the module logs in signals from multiple groups of channels at different times as they become valid on the processor bus. The module then sends all the logged-in signals to the trigger machine and to the memory of the module for storage.

In Custom clocking, the module Clocking State Machine (CSM) generates one master sample for each processor 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 when data is acquired from the Primary and Expansion bus.

Figure 3–4 shows the sample points and the master sample point when data is acquired from the Expansion bus.

Data from I/O Expansion bus is acquired as follows. When the IOSTRB~ is low the address and control signals are logged in at the falling edge of the clock (H1). At the next rising edge the XRDY~ signal is sampled and if low the Data lines are logged in. Under TMS320C3X micro clocking, IACK~ is not sampled at valid times.

The TMS320C3X support has provisions for three types of clocking options. The clock option establishes the type of bus cycle to include in, or exclude from the acquisition. The three select fields that you can choose from to customize your clocking are:

H Alternate Bus Master (ABM) Cycles, excluded or included. H Wait State Mode H Num of SW wait

Alternate Bus Master Cycles Excluded. DMA cycles are not acquired or displayed.

Alternate Bus Master Cycles Included. All bus cycles, including Alternate Bus

Master cycles are acquired.

Wait State Mode. The Wait State Mode field contains four selections that

correspond to the particular wait state mode you are using. The Wait State Modes are:

Hardware Only – The wait state depends only on the status of the external RDY~ line. The software wait state (SW Waits) are ignored.

Software Only – The wait state depends only on the number of SW Waits programmed in the Num of SW Wait field. The status of the external RDY~ line is ignored.

TMS 702 TMS320C3X Digital Signal Processor Support Instruction Manual

HW or SW – The wait state depends on either the status of the external RDY~ line, or the number of SW Waits selected in the Num of SW Wait field., whichever occurs earlier.

HW and SW – The wait state depends on both the status of the external RDY~ line and the number of SW Waits selected in the Num of SW Wait field., whichever occurs later.

Num of SW Wait. This field provides the number of SW Waits programmed in the Wait State Mode field. A total of eight SW Waits can be programmed in this field.

Alternate Microprocessor Connections

You can connect to other signals that are not required by the support so that you can analyze other signal activity in your system. 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.

Signals Not On the Probe

Adapter

For a list of signals required or not required for disassembly, refer to the channel assignment tables beginning on page 3–6. Remember that these channels are already included in a channel group. If you do connect these channels to other signals, you should set up another channel group for them.

The probe adapter does not provide access for the following signals:

Probe Adapter Circuit Description

One transparent latch chip (74FCT373C) is used to ensure that the RDY~and XRDY~ signals meet setup/hold time requirements. These requirements are needed for signals used as qualifiers. All other signals go directly to the podlets. To correctly acquire the RDY~ and XRDY~ for timing analysis, J120 must be in the T position.
