General Information 

 

The following are Generated out of CORE Generator: 

- Ethernet AVB Endpoint core netlist 

- Example design HDL top-level and associated HDL files 

- Demonstration test bench to exercise the example design 

- Documentation Directory containing Data Sheet, Getting Started Guide, and User Guide 

 

New Features 

 

- ISE 11.1 software support 

- Spartan-3, Spartan-3E, and Spartan-3A support 

 

Resolved Issues 

 

- For Spartan-3A DSP, the core contained an incorrect clock enable in the 8 KHz clock derivation logic. 

- version fixed: v1.2 

- CR 481302 

 

- MAC Header filter issues. 

- version fixed: v1.2 

- CR 480159 

- The Broadcast Address recognition logic had a pipeline delay bug: the 1st 5 bytes of the MAC DA were correctly identified. However, an error in the 6th byte incorrectly caused a Broadcast Address to be signaled. 

- A similar issue existed for the eight configurable MAC Header Filters. These are capable of recognizing the bit pattern of the first 16 bytes in a received frame. Like the Broadcast recognition bug, a bit error in the last byte of this check (the 16th byte in this case) could slip through unnoticed, resulting in a false filter match. 

 

- The core is not compliant with the P802.1AS specification for PTP frame identification. 

- version fixed: v1.2 

- CR 488623 

- PTP packets were incorrectly identified on the receiver data path using the Destination Address; they should be identified using the Length/Type field. 

 

- Out-of-date resource utilization figures were used in the Datasheet. 

- version fixed: v1.2 

 

Known Issues 

 

- none
