Measured Driver Margins May Be Smaller than Expected

Environment

    Intel® Quartus® Prime Pro Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT

Critical Issue

Description

This problem affects Arria 10 EMIF IP products.

Driver margins measured with the EMIF Debug Toolkit may be smaller than expected when using the EMIF Example Design Traffic Generator.

Resolution

The workaround for this issue is to edit the altera_emif_avl_tg_driver.sv file, and change the following line:

assign fail = ~(&pnf_per_bit_persist);

to:

assign fail = ~(&pnf_per_bit_persist) & (TG_NUM_DRIVER_LOOP == 0 ? 1\'b1 : test_complete);

This issue will be fixed in a future version.
