Chapter 4: Using the ChipScope Pro Analyzer
Reset All
To reset all the channels in the IBERT core, use IBERT_V6GTH > Reset All or click the
Reset All button in the toolbar.
JTAG Scan Rate and Scan Now
The JTAG Scan Rate toolbar and IBERT_V6GTH > JTAG Scan Rate menu options are
used to select how frequently the ChipScope Pro Analyzer tool queries the IBERT core for
status information. The default is 1s between queries, but it can be set to 250
ms, 500 ms, 1s,
2s, 5s, or Manual Scan. When Manual Scan is selected, use IBERT_V6GTH > Scan Now or
the Scan Now (or S!) toolbar button to query the IBERT core.
IBERT Console Window for Spartan-6 FPGA GTP Transceivers
To open the console for a ChipScope Pro IBERT core for Spartan®-6 LXT devices, select
Window > New Unit Windows and the core. A dialog box displays for that core, and you
can select the IBERT S6 GTP Console. Windows cannot be closed from this dialog box.
The same operation can by achieved by double-clicking on the IBERT S6 GTP Console
leaf node in the project tree, or by right-clicking on the IBERT S6 GTP Console leaf node
and selecting Open IBERT S6 GTP Console.
The IBERT Console for Spartan-6 LXT platforms is composed of the MGT/BERT Settings
Panel, the DRP Settings Panel, and the Port Settings Panel.
MGT/BERT Settings Panel
The MGT/BERT Settings panel contains a table that is made up of one or more vertical
columns and horizontal rows. Each column represents a specific active GTP Transceiver.
Each row represents a specific control or status setting.
MGT Settings
The MGT Alias setting is initially set to the MGT number of the GTP transceiver, but can
be changed by selecting the field and typing in a new value.
The Tile Location setting denotes the X/Y coordinate of the GTP transceiver in the device.
The MGT Link Status indicator is displays the status of the link detection logic that is
connected to the receiver of a particular GTP transceiver channel. If the channel is linked
(green), the measured line rate is displayed. If the channel is not linked, it displays NOT
LOCKED (red).
The PLL Status indicator shows the lock status of the PLL that is connected to the GTP. The
valid states of this status indicator are LOCKED (green) or NOT LOCKED (red).
The Loopback Mode setting is used to control the loopback mode of a particular GTP
transceiver channel. The valid choices for loopback mode are:
• None: No feedback path is used.
• Near-End PCS: The circuit is wholly contained within the near-end GTP transceiver
channel. It starts at the TX fabric interface, passes through the PCS, and returns
immediately to the RX fabric interface without ever passing through the PMA side of
the GTP transceiver channel GTP transceiver channel.
• Near-End PMA: The circuit is wholly contained within the near-end GTP transceiver
channel. It starts at the TX fabric interface, passes through the PCS, through the PMA,
back through the PCS, and returns to the RX fabric interface.
