Description The VSR_MODE_HIGH_LOSS option is available in the dropdown menu of the IP GUI for F-Tile JESD204B IP Design Examples. However, starting from Quartus® Prime Pro Edition Design Software version 25.3, this option is deprecated and no longer supported. With the updated F-Tile firmware starting in Quartus® Prime Pro Edition Design Software version 25.3, VSR_MODE_HIGH_LOSS and VSR_MODE_LOW_LOSS are treated equivalently. As a result, selecting VSR_MODE_HIGH_LOSS for hardware testing (e.g., on a development kit) allows the Design Example to compile successfully, but the SOF generation fails. Resolution Users should select VSR_MODE_LOW_LOSS. This issue is fixed in Quartus® Prime Pro Edition Design Software Version 25.3.1.Why Does the Simplex RX/TX Design Example Fail During HSSI Support Logic Generation with a QHIP_IP_PROPERTY Case Sensitivity Error in F-Tile JESD204B IP?
Description Due to a problem in Quartus® Prime Pro Edition Design Software Version 25.3, the F-Tile JESD204B IP Simplex RX/TX example design may fail with the following error in compilation: "Cannot find QHIP_IP_PROPERTY tile_ip_sip_instances with value …..." Resolution To work around this compilation error, manually remove the QHIP_IP_PROPERTY assignment from the .qip file in the Design Example folder. Steps: Navigate to the following path in the Design Example directory: intel_jesd204b_gts_<data path>/example_design/ed_synth/ip/jesd_gts_ss<data path>/jesd_gts_ss_<data path>intel_jesd<data path>/ Open the QIP file: jesd_gts_ss_<data path>intel_jesd<data path>.qip Locate and remove the line containing the QHIP_IP_PROPERTY assignment. Save the file and retry the compilation. This issue is fixed in Quartus® Prime Pro Edition Design Software Version 25.3.1.Why are Toolkit instances (ETK, TTK) not detected for Agilex® 7 F-Tile Ethernet Hard IP in System-console after device configuration?
Description In designs using multiple instances of the Agilex® 7 F-Tile Ethernet Hard IP with Toolkit support enabled (ETK and TTK), the Toolkit instances may sometimes not be detected in the System Console GUI after programming the FPGA with the design .sof file. This behavior is caused by a problem in the F-Tile Ethernet Hard IP configuration. Resolution A patch is available to fix this problem for the Quartus® Prime Pro Edition software version 25.3.1. Download and apply attached patch 1.32, which restores Toolkit visibility in the System Console GUI for the F-Tile Ethernet Hard IP. This problem is scheduled to be fixed in a future release of Quartus Prime Pro Edition software.Synthesis Critical Violation: IPC-40026 - System clock frequency mismatch
Description Due to a problem in the Quartus® Prime Pro Edition Software version 25.3, there will be a critical synthesis violation when using Agilex® 5 GTS SDI II IP with BASE and PHY mode, and set System PLL frequency to a value other than 700MHz. Resolution You can ignore this violation if the System PLL output frequency meets the minimum requirement in Table 25 of the GTS SDI II IP User Guide: SDI Mode Minimum System PLL Output Frequency HD-SDI single rate 150 MHz 3G-SDI single rate 300 MHz Triple rate SDI (up to 3G-SDI) 300 MHz Multi rate SDI (up to 12G-SDI) 600 MHz This problem is scheduled to be fixed in a future release of the Quartus Prime Pro Edition Software.Why do I see permission denied error in Windows (64-bit) when using ModelSim*- Altera® FPGA to simulate Agilex® 7 CPRI PHY IP Example Design on the Quartus® Prime Pro Edition software version 21.4?
Description The issue occurs when using ModelSim®–Altera FPGA to simulate the Agilex® 7 CPRI PHY IP Example Design on a Windows (64-bit) system. This problem does not occur when running the same simulation on a Linux system. Resolution To work around this problem: Create a new folder called temp under example testbench. Copy the MIF file into it. In the script ./example_testbench/sim_script/common/modelsim_files.tcl, revise the MIF path. lappend memory_files "[normalize_path "$QSYS_SIMDIR/../temp/cpriphy_ftile_hw__tiles__z1577a_x388_y0_n0.mif"]" Alternative: In the script ./example_testbench/sim_script/mentor/msim_setup.tcl, revise as follow.
