11. Troubleshoot and Diagnose Issues
This section describes debug methods that support debugging your design in both simulation and hardware environments. The GTS Ethernet Hard IP supports various debugging features, including:
- Diagnostic loopback modes (internal, external, MAC, PCS, and packet client)
- Status Signals
- Supported Tools (Clocking and Ethernet Toolkit)
The following troubleshooting table provides additional guidance.
