Solution

What's New 

 

Enhancements 

- Support added for Virtex-4. 

 

- Simplified the core by removing the XAUI output option (this functionality is now supported in a separate core, the XAUI LogiCORE, which users can instantiate separately). 

 

- Management blocks enhanced to use main core user clock with clock enables rather than using the MDC clock on local routing. 

 

- Statistics block now runs in the transmitter clock domain. 

 

- Enhanced Verilog demonstration test-fixture. 

 

- Enhanced MTI scripts used with demonstration testbenches to make simulation clearer. 

 

- New documentation has been added, including Getting Started Guide and User Guide. 

 

Bug Fixes 

- Fixed an issue in which frames with specific corrupt preambles would cause the following frame to be marked as bad regardless of its validity. 

 

- Corrected an issue in which valid frames would be marked as having a bad CRC if the preceding IFG had one or more error characters during the idle time. 

 

- Fixed an issue with the Length/Type Out of Range bit in the rx_statistics_vector (bit 25 in v4.0 or bit 28 in v5.0 did not correctly count undersized frames). 

 

Known Issues 

- The data sheet that is copied to the project when the XAUI v5.0 Core is generated is incorrectly named "xaui_ds365.pdf". The correct name should be "xaui_ds265". This will be fixed in the next release of the core.
