Chapter 4:
Using the ChipScope Pro Analyzer
of eight associated GTZ transceivers. Each row represents a specific DRP attribute or
address.
When the radio button at the bottom of the panel is set to
View By Attribute Name
, all the
DRP attributes display in alphabetical order. The
Radix
combo box lets you choose
between Hex (hexadecimal) and Bin (binary). To change a value, click in the text field for
the value, type in a new value, and press
Enter
. The new value is set immediately in the
MGT.
When the radio button at the bottom of the panel is set to
View By Address
, the raw
addresses are displayed in numerical order with their contents. The
Radix
combo box lets
you choose between Hex (hexadecimal) and Bin (binary). To change a value, just click in
the text field where the value is, type in a new value, and press
Enter
. The new value is
immediately set in the MGT.
Port Settings Panel
The
Port Settings
panel contains a table that is made up of one or more vertical columns
and horizontal rows. Each column represents a specific active GTZ transceiver octal group.
Each row represents a specific MGT port. Not all ports are displayed because some are
used in the IBERT design to send and receive data.
The
Radix
combo lets you choose to display the value in either Hex (hexadecimal) or Bin
(binary). Some ports are read-only and not editable. Those cells in the table look like labels.
The ports in the table that are editable look like text fields, and placing the cursor in those
fields, typing a new value, and pressing
Enter
writes the new value to the MGT
immediately.
RX Margin Analysis Panel
Use the
RX Margin Analysis
panel to set up a channel test that sweeps through various
transceiver settings to help find the optimal channel settings. The
TX
and
RX
settings
shown in this panel are for the same GTZ transceiver. Sweeping through both TX and RX
settings only works if the transceiver is set to one of the near-end or external loopback
modes. Sweeping through RX parameters only can be performed when the corresponding
TX endpoint for the link resides in a different device or a different transceiver in the same
device.
The tabbed
Sweep Test Settings
panel consists of four sections: MGT/Parameter Settings,
Scan Settings, Test Controls, and Test Results.
MGT/Parameter Settings
Use the
MGT
combo box to select the GTZ transceiver that will participate in the sweep
test.
Note:
Only one GTZ transceiver can be swept at a time.
Before setting up the sweep test, set up the sweep parameters. While you can use any GTZ
parameters during the parameter sweep operation, the most useful GTZ transceiver
parameters available for sweep are the defaults:
•
TX Diff Swing
•
TX Pre-Cursor
•
TX Post-Cursor
To add or remove items in the table, click the
Add/Remove Parameters
button. This opens
a dialog box with all available ports/attributes on the left, and the ones to sweep on the
