1.1. GTS Auto-Negotiation and Link Training for Ethernet IP v4.0.1

Table 1.  v4.0.1 2025.08.11
Quartus® Prime Version Description Impact
25.1.1 Added support for High Voltage (HVIO) PLL for Agilex™ 5 E-series devices for single rate configuration with MAC Avalon® -ST client interface.
  • Device Group B (10G rate): Simulation, Compilation, Timing and Hardware
  • Device Group A (25G rate): Simulation, Compilation, and Timing
To use HVIO PLL option, you must regenerate the IP.
Added AN/LT feature support for Agilex™ 3 C-Series devices (Simulation, Compilation, and Timing). You must regenerate the IP to use the AN/LT feature in Agilex™ 3 C-series devices.
For VCS* MX, QuestaSim* , and Riviera-PRO* , the Ethernet design example simulation run scripts use polished simulation models by default for the ANLT/PTP/default modes of operation. However, for Xcelium* , the script uses the non-polished simulation models for all modes, including the ANLT/PTP/default modes. This improves the simulation compile and run times. You need to regenerate the design example to use polished simulation models.
Minor bug fixes.
