Embedded Tri-mode Ethernet MAC Wrapper v3.1 - IDELAYCTRL logic is incorrectly reset for RGMII interfaces

描述

General Description:

When using the Embedded Tri-mode Ethernet MAC Wrapper v3.1 with the RGMII interfaces, the reset of the IDELAYCTRL module is incorrectly tied to ground. According to the Virtex-4 User Guide, the IDELAYCTRL must be reset after configuration.

解决方案

A patch is available which correctly resets the IDELAYCTRL following configuration. To obtain this fix, install the patch that is available in the Embedded Tri-mode Ethernet MAC Wrapper v3.1 Core Release Notes and Known Issues Answer Record (Xilinx Answer 21903) and then regenerate the wrappers.
