History
05-Feb-18 New manual.
Introduction
Lauterbach Development has enlarged its trace tool portfolio for serial trace ports. The new device called
PowerTrace Serial extends the range of supported lane data rates to 12.5Gbps and the possible lane count
up to eight. Furthermore, new interfaces are supported e.g. PCIe, which allow trace data transfer over
common interfaces.
PowerTrace Serial is not just the successor of the serial preprocessor. The well know serial preprocessor in
conjunction with the PowerTrace 2 is still the preferred tool for low speed and low lane count applications.
However in case of lane speeds above 6Gbps and/or lane counts higher than four, the PowerTrace Serial will
be the preferred tool.
Higher speeds are always combined with higher demand on system design. New interfaces require digging
into new papers of peripheral components. There is more work to do and higher potential of malfunction.
This User’s Guide intends to flatten the path to a well working Gigabit-trace setup.
Intended Audience
This manual categorizes users into the following groups:
•Serial trace average users: In addition to reading chapter Installation, they should focus on the
sections Trace Port Utilization and Basic Checks.
•Serial trace advanced users: As they are familiar with the above chapters and sections,
advanced users should also read the sections Advanced Checks.
Prerequisites
• This document assumes that you already have the PowerTrace Serial hardware and a fully
functional TRACE32 software installation.
• For some trace port types (e.g. PCIe), you need a different accessory set.

Hardware Installation
PowerTrace Serial
1. Connect the PODBUS EXPRESS IN connector to the PODBUS EXPRESS OUT connector of
the PowerDebug II / PowerDebug Pro interface. Please ensure correct positioning. The
connectors must be clean and without any damage.
2. Connect the flex cable and, if necessary, the debug cable to Serial Port 0 or Serial Port 1 of the
PowerTrace Serial.
Check the connector orientation of tool and target, there are two 45° corners [A] and two 90° corners
[B]:
The marker of pin 1 [C] of the plug is easy to miss, but is located close to one 45° corner [A]. For
better illustration the picture below is rotated of 180°:

The flex cables are labeled to make the installation easier:
Serial Port 0: The debug cable can be connected to the PowerTrace Serial module or directly to the
target depending on the target trace connector pin-out.
Serial Port 1: The debug cable must be connected to the target directly or

Adapter for PCIe Slot Card (LA-3525)
The active adapter card is used to adapt PC-like targets with trace data coming via PCIe. A special analog
repeater component amplifies the electrical signal and improves the data eye. The component is transparent
to target and tool. It can work in automatic configuration mode or manual configuration mode for
PCIe Gen1,2 and 3.
The form factor follows the standard for PC slot-in cards. The card can be plugged into standard 16-lane-
slots, 8-lane-slots and in case of special open-frame connectors also into 4-lane-slots and 1-lane-slots. If
necessary the metal plate can be removed.
The adapter will be shipped in auto-configuration-mode which will work for most
of the targets. Configuration changes (e.g. deemphasis) should be done
carefully and knowledge of high-speed signaling techniques is necessary.

Configuration Switches
Equalization and Deemphasis can be configured separately for RX lane [0-3] and RX lane [4-7] and
TX lane [0-3] and TX lane [4-7]. The configuration switches are grouped and can be set to on (1) and off (0).
Three switches form a mutual group, e.g. switch[1..3]=> parameter EQ0. Within a group only one switch
must be on.
Driver settings for RX and TX will match in most cases.

Configuration Guide
Target specific adapter configuration might be necessary, if
• it is not possible to get a PCIe link
• the lane speed is below the maximum possible
• the PCIe error rate is high => high bandwidth reduction
Start with the first configuration (#1) and increase step by step (#2 => #3 ...). To verify the configuration the
data eye scanner should be used (Analyzer.ShowFocusEye).
Always first disable the switches before you enable the next configuration. Don’t
have more than one switch enabled within a group. Changing the configuration
must be done like this:
100 : current configuration
000 : set temporary configuration
001 : set final configuration
