18.104.22.168.6. Driver Margining Tab
Driver Margining is supported only when a memory interface meets all of the following criteria:
- Has a TG IP (altera_emif_tg_avl) connected to it (that is, not the configurable traffic generator).
- Does not have ECC enabled.
- Has ISSPs enabled in the project’s .qsf file.
To run driver margining, click the Run Driver Margining button at the top left corner 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 test results are displayed in the table when the test is completed.
