Using the ChipScope Pro Analyzer
•
RX EQ
The sweep parameters can be initialized in one of two ways:
•
Click the
Clear All Parameters
button to clear all parameters to the Select… option.
•
Click the
Set Parameters to Current Values
button to set the parameters to their
current values on the MGT/BERT Settings panel.
The order of the parameters in the Sweep Parameter table dictates how the parameters are
swept. The values of the parameters near the top of the table are swept less frequently than
the parameters near the bottom of the table. In other words, the parameters near the top of
the table are in the outer loops of the sweep algorithm while the parameters near the
bottom of the table are in the inner loops of the sweep algorithm.
Each parameter must be set up with a start and end value. The order of the parameter
values cannot be changed. After you select the start value, the end values available for
selection change automatically to include only valid selections. If you do not want to
sweep through a parameter, set the start and end values for that parameter to the same
value. The Sweep Value Count column indicates how many values are swept through for
a particular parameter. After all sweep parameters have valid start and end values, the
total number of sweep iterations are shown in the Total Iterations field.
To add or remove items in the table, click the
Add/Remove Parameters
button. This opens
a dialog box with all available ports/attributes on the left, and the ones to sweep on the
right. To add new parameters to sweep, click it in the left hand list, and click the
>
arrow
button. To remove a parameter to sweep, click it in the right-hand list, and click the
<
arrow
button. To specify the sweep order of the parameters, click it in the right hand list, and then
the
Up
or
Down
buttons. To revert the sweep attributes and their order to the default
setting, click the
Reset to Default
button. Click
OK
to apply the settings, or
Cancel
to exit
without saving.
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 the sweep test has been set up, the test can be started by clicking the
Start
button.
After the
Start
button is clicked, the sweep parameter table are 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
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
window.
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.
