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
, and the
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.
