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- Out-of-date resource utilization figures were used in the Datasheet.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