Using the ChipScope Pro Analyzer
Sampling Point Region
The sampling point is the horizontal point within the eye to sample. Visualize on transition
region at the far left, and the next at the far right. The RX Sampling Point is one of 128
discrete sampling positions. In the
Sampling Point Region
section, choose the left and
right edges of the sampling region.
Test Controls
After setting up the sweep test, start the test by clicking the
Start
button. The sweep
parameter table is then disabled, and the test starts running.
As the sweep test runs, the current sweep result file, current iteration, elapsed time, and
estimated time remaining status indicators are displayed. The sweep results are shown in
the text area near the bottom of the screen. The sweep test can be paused by clicking on the
Pause
button or stopped completely by clicking on the
Stop & Reset
button.
The results from a sweep test are displayed in the
Test Results
panel and are also sent to a
sweep test result file. Clicking on the
Log File Settings
button brings up the dialog box.
You can set both the location of the file and the number of sweep iterations stored in each
file. If the total number of sweep iterations exceeds the file limit, multiple files with starting
iteration number appended to the base file name are created in the same directory as the
initial result file.
Test Results
The
Test Results
panel shows the current iteration, the elapsed time, and the estimated
time remaining. Below this status information are the test results for each sweep of the
sampling point region.
Sweep Test Log
The Sweep Test Log tabbed panel is always enabled and contains the running log of the
sweep test results. The information on this panel is shown using a text-only display. The
results of the sweep test are also stored in a CSV log file.
IBERT Spartan-6 FPGA GTP Toolbar and Menu Options
IBERT Console Options
The IBERT Console Options dialog allows you to select which columns and rows to
display in the IBERT Console. The left-hand panel selects the MGTs by location. Use the
Check All
and
Uncheck All
buttons to select all or none of the MGTs.
The right-hand panel selects which rows are displayed in the MGT/BERT settings. Use the
Check All
and
Uncheck All
buttons to select all or none of the rows. 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, TX PLL Status, RX PLL Status, Loopback
Mode, Channel Reset, TX Error Inject, Rx Sampling Point, TX Data Pattern, RX Data
pattern, Rx Bit Error Ratio, Rx Received Bit Count, Rx Bit Error Count, BERT Reset,
TXUSRCLK2 Freq, and RXUSRCLK2 Freq.
Import/Export Dialog
The Import/Export Dialog allows you to 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, use
IBERT_S6GTP
>
Import/Export Wizard
or click the
Import/Export Wizard
button in the
toolbar.
