11.5.4.5. Driver Margining Tab

The driver margining feature lets you measure margins on your memory interface using a driver with predefined traffic patterns.

Margins measured with this feature are expected to be smaller than margins measured during calibration, because this traffic pattern is longer than those run during calibration, and is intended to stress the interface.

To use driver margining, press Run Driver Margining, at the top-left of the tab. The toolkit then measures margins for DQ read, DQ write, and DM. The process usually takes a few minutes, depending on the margin size, the interface size, and the duration of the driver tests.

The system displays the test results in the table when the test has completed.
