Have the Arria® 10 PCI Express* Testbench required simulation files changed in version 24.2 of the Quartus® Prime Design Software?
Description Yes, as part of the ongoing improvements and streamlining of the Quartus® Prime Design Software core device family models (altera_mf etc.) the PCI Express* link-partner root-port BFMs that shipped as part of the altera_pcie_a10_tbed (IP version 19.1) were updated starting in version 24.2 to use Arria® 10 FPGA based primitives rather than the previously used Stratix® II FPGA primitives without a corresponding IP version increase. Attempting to use device libraries compiled from newer versions of Quartus® Prime Design Software with a testbench generated from an older version of the Quartus® Prime Pro software may lead to runtime errors from simulators about invalid module parameters of the form: Error! Unknown INTENDED_DEVICE_FAMILY=Stratix II. Resolution To resolve this problem, it is recommended to always re-generate Altera IP with the same version of the Quartus® Prime Pro software being used.Why does design compilation in the Quartus® Prime Pro Edition software version 25.3 and earlier fail during the fitter stage when the “Remove Redundant Logic Cells” option is enabled, and the F-Tile Dynamic Reconfiguration Suite IP is used in the design?
Description Many users enable the “Remove Redundant Logic Cells” option to optimize their designs for area and speed. However, when this Advanced Synthesis setting (REMOVE_REDUNDANT_LOGIC_CELLS) is turned on globally for F-Tile designs —particularly those that include the F-Tile Dynamic Reconfiguration Suite IP— it can inadvertently remove essential support logic (QTLG-generated logic) required for proper transceiver tile operation. As a result, design compilation in the Quartus® Prime Pro Edition software version 25.3 and earlier may fail during the fitter stage with errors related to transceiver logic placement, such as: Error (14566): The Fitter cannot place 2 periphery component(s) due to conflicts... Error (175001): The Fitter cannot place 1 HSSI_PLDADAPT_TX. The “Remove Redundant Logic Cells” option can be enabled in two ways: Through the Quartus Prime Pro Edition software GUI, as described in the Quartus Prime Pro Edition User Guide, section 1.19.1 Advanced Synthesis Settings. By adding a global assignment in the Quartus project’s QSF file: set_global_assignment -name REMOVE_REDUNDANT_LOGIC_CELLS ON Resolution To prevent fitter errors during compilation for F-Tile designs, it is essential to preserve the Quartus Tile Logic Generated (QTLG) support logic from being removed by the “Remove Redundant Logic Cells” optimization. This can be achieved by following these steps: Enable global redundant logic optimization for most of the design: set_global_assignment -name REMOVE_REDUNDANT_LOGIC_CELLS ON Override the setting for the transceiver support logic (Tile IP) to ensure critical blocks are retained: set_instance_assignment -name REMOVE_REDUNDANT_LOGIC_CELLS OFF -to top_auto_tiles Note: Replace top_auto_tiles with the actual instance name used in your design. By selectively disabling redundant logic removal for the Tile IP, you safeguard the necessary support logic while optimizing the rest of your design, thereby avoiding fitter errors during compilation. This problem is scheduled to be fixed in a future release of the Quartus Prime Pro Edition software.Error: niosv_g_dcache.sv: part-select direction is opposite from prefix index direction
Description Due to a problem in the: Quartus® Prime Pro Edition Software version 24.3.1, 25.1, and Quartus® Prime Standard Edition Software version 24.1 When the Nios® V/g processor is configured with No Data Cache and enabled with Error Detection and ECC Status Reporting, performing Analysis and Synthesis fails with the error "niosv_g_dcache.sv: part-select direction is opposite from prefix index direction". Note that this issue has no relationship with No Instruction Cache. Figure. Nios® V/g Processor Setting to Replicate the Error Resolution To work around this error, Select 1Kbytes Data Cache. Apply a Peripheral Region that covers the whole Nios® V processor’s data_manager address map Enable Error Detection and ECC Status Reporting. By implementing Peripheral Region, the above settings can emulate an ECC-enabled Nios® V processor system that operates without caches. Figure. Workaround (in this example, the whole Nios® V processor’s data_manager address map is 1GB) This problem is scheduled to be fixed in a future release of the Quartus® Prime Edition Software.Why isn’t a programming (SOF) file generated for the F-Tile Dynamic Reconfiguration Suite IP available for Example Designs when using the Quartus® Prime Pro Edition software versions 25.3 and earlier?
Description Due to starting from the Quartus® Prime Pro Edition software version 25.3 and earlier, it is compulsory to connect all the I/O ports to the correct PIN location. If any of the design I/O ports are floating and not properly connected, Quartus software will not be able to generate the programming file for the design compiled. This is mentioned in the Quartus Prime Pro Edition User Guide version 25.1.1 in 1.2. Generating Secondary Programming Files and provide the guidelines to the user on how to fix the Quartus software critical warning and successfully create the programming file for your design. Why don’t I get a programming file when I compile with the.... Similar programming (SOF) file generation problem you may observe when you generate the F-Tile Dynamic Reconfiguration Suite IP Example Designs by selecting Target Development Kit with option 1) Agilex™ 7 FPGA I-Series Transceiver-SoC Development Kit (Production 1 4xF-Tile) DK-SI-AGI027FA or 2) Agilex 7™ FPGA I-Series Transceiver-SoC Development Kit (Production 2 4xF-Tile) DK-SI-AGI027FC. As shown in the figure below. Resolution As a workaround, generate the F-Tile Dynamic Reconfiguration Suite IP Example Designs by selecting the Target Development Kit with the option you want and compiling the design. Review the I/O Assignment Warnings report, found in the Place sub-section of the Fitter section of the compilation report. Alternatively, review the <revision>.fit.plan.rpt report file. For any pins in the I/O Assignment Warnings report that are reported as “Missing location assignment” or “Missing I/O standard,” add the appropriate location or I/O standard assignment. For help making these assignments, refer to Assigning I/O Pins. After adding any required assignments, recompile the design to generate a programming file. This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition software.Why is the external loopback test failing for the GTS Dynamic Reconfiguration Controller IP in the GTS PMA/FEC Direct PHY example design?
Description Due to a problem in the Quartus® Prime Pro Edition software version 25.1.1 and 25.3, you may notice that the external loopback test is not working correctly for the GTS Dynamic Reconfiguration Controller IP for the GTS PMA/FEC Direct PHY example design. This is due to incorrect settings in the hardware tcl scripts inside the “hwtest” folder. You may notice the external loopback test shows “DR Test Passed” in the system console; however, it does not change the DR profile for GTS PMA/FEC Direct PHY IP. Resolution As a workaround, modify the tcl script file as shown below: Go to “hardware_test_design/hwtest” folder: Replace the “dr_ctrl_csr_reg_map.tcl ” file inside the “hwtest/src” folder with the attached file. Replace the “dr_dphy_test.tcl” file inside the “hwtest/tests” folder with the attached file (hwtest.zip). This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition software.Why doesn’t the output frequency of the System PLL match the setting in the GTS System PLL Clocks IP?
Description Due to a device problem, some reference clock frequency options in the dropdown list in the IP are no longer valid for certain output frequencies. Selecting the invalid reference clock options will result in incorrect System PLL output frequencies. However, the System PLL lock status signal remains asserted. Resolution Download the TCL script (find_mcnt.tcl) to determine whether the reference clock frequency selected in the GTS System PLL Clocks IP is valid. If the reference clock frequency is not valid, the script recommends the following workarounds: List of alternate reference clock frequencies while keeping the same output frequency. Two alternate higher System PLL output frequencies while keeping the same reference clock frequency. You need to run the transceiver channels driven by the impacted System PLLs in custom cadence mode. In certain cases, the script will suggest that the same output & input clock frequencies can be retained. This option is possible only if you install the patch for the Quartus® Prime Pro Edition Software version 25.3 or migrate to future Quartus Prime Pro Edition Software versions. Copy the TCL script (find_mcnt.tcl) to each of the generated IP folders of the GTS System PLL Clocks IP in your Quartus Prime Pro Edition Software project. For the Linux* operating system, change directory to the IP folder and execute the command "tclsh find_mcnt.tcl". For Windows* operating system, run the script from the Tcl Console within the Quartus Prime Pro Edition Software GUI. A patch is available to fix this problem for the Quartus Prime Pro Edition software version 25.3. Download and install Patch 0.15 from the files below. Recommended actions: Customer Design Status Recommended Actions Design not impacted If the design is final and there is no plan to change the System PLL output frequency or reference clock frequency in future revisions, no further action is needed. If you change the design in the future, either migrate your design to Quartus Prime Pro Edition Software versions 25.3.1 or later, or install the patch for Quartus Prime Pro Edition Software version 25.3. Design impacted Implement one of the workarounds suggested. In addition, migrate your design to the Quartus Prime Pro Edition Software version 25.3.1 or later. If you need to keep your design in the Quartus Prime Pro Edition Software version 25.3, install the patch, re-generate the GTS System PLL Clocks IP, and recompile your Quartus project. The invalid reference clock frequency options will be removed in a future Quartus Prime Pro Edition Software version.Why does the F-Tile Triple-Speed Ethernet IP Design Example fail during simulation on Windows using ModelSim* in the Quartus® Prime Pro Edition Software version 24.3?
Description Due to a problem in the Quartus® Prime Pro Edition software version 24.3, the F-Tile Triple-Speed Ethernet (TSE) IP Design Example variant - “10/100/1000 Ethernet MAC Design Example with 1000BASE-X/SGMII 2xTBI PCS with F-Tile FGT Transceiver” - may fail during simulation on Windows platforms using ModelSim*.

Why don’t I get a programming file when I compile with the.... A similar programming (SOF) file generation problem is observed when you generate the GTS Ethernet Hard IP with PTP-enabled example designs in Dynamically Reconfigurable. This is due to a missing pin assignment for the “i_todsync_sel” port. Resolution As a workaround, modify the “intel_eth_gts_hw.v” file as shown below: Comment out “input wire i_todsync_sel” port in the top entity Declare it as internal “wire i_todsync_sel=1'b1;” Recompile the design. This problem is scheduled to be fixed in the future release of the Quartus® Prime Pro Edition software.Why doesn't the Triple-Speed Ethernet (TSE) FPGA IP for all devices always maintain a negative running disparity during idle cycles as per the IEEE 802.3 standard?
Description Due to a problem in the Quartus® Prime Pro Edition software, when using the Triple-Speed Ethernet (TSE) FPGA IP across supported device families, the transmitter may not maintain a negative running disparity during idle cycles as defined in the IEEE 802.3 standard. Specifically, the first IDLE sequence after a packet or configuration set is not always generated as /I1/, which is required to restore the running disparity to negative. Resolution A patch is available to fix this problem for the Quartus® Prime Pro Edition software version 24.1 for Agilex™ 7 FPGA F-Series E-Tile devices. Download version 24.1 patch 0.47 for Windows and Linux below This patch ensures the transmitter maintains negative running disparity for Agilex™ 7 FPGA F-Series E-Tile devices by inserting the first idle sequence (/I1/) whenever required, followed by all subsequent idle sequences (/I2/), maintaining compliance with the IEEE 802.3 standard.
