an interpolation between the values, and displays each scanned point as one block of color
according to the BER value.
If the 1D Bathtub scan algorithm is used, each plot corresponds to a sweep across the unit
interval (UI) of the received signal. The left and right edges of the data plot correspond to
the Horizontal settings in the Scan Settings panel. In 1D Bathtub mode, the main
measurement that is observed in the sweep test plot is the width of the UI "opening" of the
active plot at the lowest measured bit error ratio (BER). Use the selection buttons in the plot
list area on the right side of the Sweep Test Plots panel hide or show each plot. Use the
right-click menu options to rename or re-color each plot and set a plot as "active". The
horizontal and vertical markers help you take measurements on the "active" plot. The
horizontal marker can be moved up and down and the vertical markers can be moved left
and right by clicking and dragging them.
Sweep Test Info: The Sweep Test Info panel is also enabled only after the sweep test has
stopped running. The tabular data shown in the Sweep Test Info panel corresponds to the
data shown in the graphical Sweep Test Plots panel. Each row in the table corresponds to
a single sweep test plot.
In 2D Full Scan algorithm mode, the table columns correspond to the following:
•
•
In 1D Bathtub scan algorithm mode, the table columns correspond to the following:
•
•
•
The remaining columns correspond to the parameter value settings that were used to
create the corresponding sweep test plot. Click the column header to sort the rows in the
sweep test panel.
Note:
clicking the Opening at the Lowest BER Level column header.

IBERT Console Options
The IBERT Console Options dialog box allows you to select which columns and rows to
display in the IBERT Console. The left panel selects the MGTs by location. Use the Check
All and Uncheck All buttons to select all or none of the MGTs.
The right panel selects which rows are displayed in the MGT/BERT settings. The Default
button sets up the Console to display the basic set of rows needed to determine the health
of the channels. The Default rows are Tile Location, PLL Status, Loopback Mode,
Channel Reset, TX Polarity Invert, TX Error Inject, TX Diff Output Swing, TX Pre-
Cursor, TX Post-Cursor, TX Data Pattern, TXUSRCLK Freq, and TXUSRCLK2 Freq.
Import/Export Dialog
In the Import/Export dialog box, you can save and recall settings from a specific MGT or
apply the setting of one MGT to others in the design. To import or export settings, select
