scope:

This document contains a list of checks that can be used during the verification or debug stages of development to check that accesses to a DDR4 DRAM adhere to JESD79-4B. These checks are derived from JESD79-4B. The intent of this document is not to supplant the JESD79-4B document, but to help consolidate the checks into a single easy to read document. This document was not intended to indicate how a protocol check measurement would be made, but what measurement would be made. The how can differ based on the testing requirements or the equipment at hand. This document is not a definitive list as other DDR4 protocol checks do exist and can be added to this document during subsequent revisions.
