Why o_rx_pcs_fully_aligned does not assert for 40GE-4 Advanced mode F-Tile Ethernet Hard IP design when Custom Ethernet line rate > 63Gbps?
Description Due to a problem in the Quartus® Prime Pro Edition Software version 25.3 and earlier, you might observe o_rx_pcs_fully_aligned does not assert for the F-Tile Ethernet Hard IP design with below configurations: Advanced mode: Enabled Ethernet mode: 40GE-4 Custom Ethernet line rate: > 63 Gbps Resolution There is no workaround. There is no fix planned in the future. When advanced mode enabled for 40GE-4 design, supported custom Ethernet line rate is: 41.25~63 Gbps.How do I enable debug endpoint for transceiver toolkit (ADME) for the F-Tile 25G Ethernet Soft-IP to use the Transceiver Toolkit?
Description The F-Tile 25G Ethernet IP (alt_e25_f) does not expose the "Enable debug endpoint for transceiver toolkit" option in the IP Parameter Editor GUI. As a result, users cannot enable Transceiver Toolkit access through the standard IP configuration interface. Resolution To enable debug endpoint for transceiver toolkit for the F-Tile 25G Ethernet IP, use the following workaround: To enable the debug endpoint for the Transceiver Toolkit, use the following workaround: Open the .ip file for the F-Tile 25G Ethernet Soft IP. Locate the ENABLE_ADME_GUI parameter. Change its value from 0 to 1. Save the .ip file. Regenerate the IP. Note: This workaround modifies a hidden parameter that is not officially available in the GUI. The parameter implementation may change in future releases. After upgrading Quartus® Prime software, verify that the functionality continues to operate as expected.
Why does EMIF for HPS LPDDR4 fail calibration on the Agilex® 5 FPGA and SoC FPGA?
Description In the Quartus® Prime Pro Edition Software 24.3, when configuring the Agilex® 5 FPGAs and SoC FPGAs with the EMIF for HPS IP and LPDDR4 device implemented as dual rank (2 chip selects), dual channels (i.e., 4 dies each being 16 Gbit in density), calibration can fail. Resolution This issue is fixed in 24.3.1 Quartus® Prime Pro Edition Software release. quartus-24.3-0.11-windows.exe quartus-24.3-0.11-linux.run quartus-24.3-0.11-readme.txtWhy is the eCPRI FPGA IP unable to run on hardware using Stratix® 10 E-Tile with the Nios® V Processor for FPGA and turn on the interworking function (IWF)?
Description Due to a problem in the eCPRI FPGA IP version 3.0.2 in the example design, you may find that there is an error shown at the 10G transaction after changing the dynamic reconfiguration process from 25G to 10G. Resolution There is currently no plan to fix this behavior in a future Quartus® Prime release.Why Can't I Program Using Active Serial Programming with my USB Blaster III?
Description Due to a firmware issue the USB Blaster III Development cable may not have the correct product ID and may inadvertently disabled the active serial programming feature. Resolution To resolve this issue the Product ID of the cable should be updated to (6023). Perform the following steps on Windows to update the ID.

Description Due to a problem in the Quartus® Prime Pro Edition software version 25.1.1 and earlier, Transceiver Toolkit (TTK) is currently not supported for Dual Simplex designs for Agilex® 5 FPGAs. As a result, users may not be able to detect the instance through the System Console or bring up the TTK, which can also impact register access and debugging activities. Resolution This problem is fixed beginning with the Quartus Prime Pro Edition software version 25.3.1.Why are tx_reset_ack and rx_reset_ack signals not going high in my dual simplex design?
Description Due to a problem in the Quartus® Prime Pro Edition software version 25.1.1 and earlier, you will observe a problem where the tx_reset_ack and rx_reset_ack signals do not go high when you enable the Avalon® memory-mapped interface only for TX Simplex IP or only for RX Simplex IP in your Dual Simplex design. Resolution To work around this problem, you need to enable the Avalon memory-mapped interface for both TX and RX Simplex IP. This problem is fixed beginning with the Quartus Prime Pro Edition software version 25.3.Why is the o_rx_pfc port enabled for longer durations than normal when generating designs at 400G SIP using the F-Tile Ethernet Hard IP with Priority Flow Control (PFC) enabled?
Description Due to a problem in the Quartus® Prime Pro Edition software version 25.3, you may see longer durations of “o_rx_pfc” port enabled in the example designs generated using the F-Tile Ethernet Hard IP at data rates of 400G SIP with PFC enabled. When PFC is enabled, if packets received are more than the maximum configured frame size of the receiver, along with which if packet truncation is also enabled on the receiver side, then the packets are truncated, causing data_valid to deassert. This deasserted data_valid signal is affecting the counters of o_rx_pfc to stretch the pause signal duration. Resolution This problem is fixed beginning with the Quartus Prime Pro Edition software version 25.3.1.Why is there a mismatch between the sideband information field of the Scalable Scatter-Gather DMA IP D2H ST responder descriptor and the error bit of the d2h_st_tuser signal?
Description Due to a problem in the Quartus® Prime Pro Edition software version 25.1 and earlier, when Enable TUSER to SOP mapping feature for D2H_ST Port parameter is disabled and the D2H ST DMA data transfer is not aligned to the D2H ST device port data width, the Scalable Scatter-Gather DMA IP may observe incorrect sideband information (user-defined error) of the D2H ST responder descriptor as compared to the error bit of D2H AXI-ST Subordinate d2h_st_tuser input signal. Resolution The problem has been fixed starting with Quartus® Prime Pro Edition software version 25.1.1.
