Using the ChipScope Pro Analyzer
The
RX Bit Error Count
field contains a running tally of the number of bit errors detected.
This count resets when the
BERT Reset
button is pushed.
The
BERT Reset
button resets the bit error and received bit counters. It is appropriate to
reset the BERT counters after the GTP transceiver channel is linked and stable.
Clocking Settings
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.
The
RXUSRCLK Freq (MHz)
indicator shows the approximate clocking frequency (in
MHz) of the RXUSRCLK 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
RXUSRCLK2 Freq (MHz)
indicator shows the approximate clocking frequency (in
MHz) of the RXUSRCLK2 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 are displayed in alphabetical order. The
Radix
combo box lets you choose
between Hex 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 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 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.
