Chapter 4:
Using the ChipScope Pro Analyzer
The
TXUSRCLK Freq (MHz)
indicator shows the approximate clocking frequency (in
MHz) of the TXUSRCLK port of the GTP transceiver. The accuracy of this status indicator
depends on the frequency of the system clock that was specified at compile time.
The
TXUSRCLK2 Freq (MHz)
indicator shows the approximate clocking frequency (in
MHz) of the TXUSRCLK2 port of the GTP transceiver. The accuracy of this status indicator
depends on the frequency of the system clock that was specified at compile time.
DRP Settings Panel
The
DRP 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 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 he 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 GTP transceiver. 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 GTP 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 GTP transceiver that will participate in the sweep
test.
Note:
Only one GTP transceiver can be swept at a time.
