Known Issues

- When attempting to open the User Guide file provided by COREGen, a number of PDF errors occur, including missing images. See the User Guide provided online at:

http://www.xilinx.com/aurora/aurora_member/ug061.pdf.
NOTE: You must be a registered Aurora Member to gain access to this document.

- The INIT_CLK, PMA_INIT and ERROR_COUNT ports have not been locked in the UCF file. Lock the INIT_CLK to an oscillator on the board and the PMA_INIT to a push-button. The ERROR_COUNT port has to be constrained to LEDs.

- A Calibration Block for the MGT must be used with ES Devices. Refer to the Calibration Block User Guide (UG090), or contact your FAE for more details and instructions on how to connect the module to the MGTs DRP and other ports. The MGTs in the Aurora module are instantiated in the "mgt_wrapper.v/.vhd" file. This file can be modified to instantiate and connect the DRP module.

- As characterization of the Virtex-4 MGT progresses, there are recommendations for some attribute settings that are different from the default values in ISE 7.1i. These recommended settings could be different based on the line rate. For 2.5 Gb/s to 3.125 Gb/s, refer to (Xilinx Answer 21672) and (Xilinx Answer 21673). These settings are valid for Aurora at the specified data rates.

- ModelSim 6.1 fails with error: "Fatal: (vsim-3420) Array lengths do not match...." For more details, see (Xilinx Answer 21910).
