MIG 7 Series and Virtex-6 DDR3/DDR2 - UG586 and UG406 have incorrect signal descriptions for the native interface "cmd" signal

描述

For both the Virtex-6 and 7 series FPGA MIG DDR3/DDR2 designs, the "cmd" signal is the Native Interface input that selects the command for the current request.

In the Virtex-6 and 7 series FPGA Memory Interface User Guides (UG406 and UG586), the codes for the "cmd" bus are incorrect; showing a read is signified by "000" and a write by "001".

解决方案

This will be resolved in a later revision of these two documents.

Be sure to signify a read with "001" and a write with "000" when interfacing to the Native Interface. The tables for the app_cmd input to the User Interface are correct.
