Known and Resolved Issues
The following table provides known issues and resolved issues for the Tri-Mode Ethernet MAC core, starting with v6.0, initially released in the Vivado 2012.1 tool.
Note: The "Version Found" column lists the version the problem was first discovered.
The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
| Answer Record | Title | Version Found | Version Resolved |
|---|---|---|---|
| NA | Fixed Timing-10 Methodology violations | v9.0 (Rev. 16) | v9.0 (Rev. 17) |
| NA | Versal RGMII mode: Fixed delay values not loaded for ODELAY elements on RGMI TX_CTL and TXD | v9.0 (Rev. 15) | v9.0 (Rev. 16) |
| NA | Fixed bug in AVB RTC clock logic which results in the RTC clock second and nano-second fields being out of sync when the nano-second field rolls over | v9.0 | v9.0 (Rev.10) |
| NA | Fixed bug in Demo testbench for 2.5G, which wrongly flagged a frame check error during user injected error | v9.0 | v9.0 (Rev.9) |
| (Xilinx Answer 67273) | Tri-Mode Ethernet MAC v9.0 (Rev.4) - 63-byte frames are not counted correctly | v9.0 (Rev. 4) | See Answer Record |
