ChipScope Pro Analyzer Features
The
RXUSRCLK2 Freq (MHz)
indicator shows the approximate clocking frequency (in
MHz) of the RXUSRCLK2 port of the GTX 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 GTX 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 are displayed in alphabetical order. 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.
When the radio button at the bottom of the panel is set to
View By Address
, the raw
address 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 GTX 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 box 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.
Sweep Test Settings Panel
The Sweep Test Settings panel is used to set up a channel test that sweeps through various
transceiver settings. The TX and RX settings are for the same GTX 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 Sweep Test Settings tabbed panel consists of four sections: the Parameter Settings.
section, the Sampling Point Region Section, the Test Controls section, and the Test Results
Section.
Parameter Settings
Setting up the sweep test first involves setting up the sweep parameters.
The GTX transceiver parameters that are available for sweep default to the following:
•
TX Diff Swing
•
TX Pre-Emphasis
•
TX Post-Emphasis
