Description Due to a problem in the Quartus® Prime Pro Edition Software version 26.1 or earlier, you might see that the bus ordering is reversed in the Technology Map Viewer. This problem occurs when a design contains a Block Design File (BDF) whose output bus is connected to a SystemVerilog HDL packed array from a top-level SystemVerilog HDL module. For example, the expected mapping in the Technology Map Viewer is: inst0 -> Out[0] inst1 -> Out[1] inst2 -> Out[2] inst3 -> Out[3] However, the actual mapping after compilation in the Technology Map Viewer become: inst0 -> Out[3] inst1 -> Out[2] inst2 -> Out[1] inst3 -> Out[0] Resolution To work around this problem, do one of the following: Convert the BDF file to Verilog HDL or VHDL. Open the BDF file in the Quartus® Prime Standard Edition Software. Select File > Create / Update > Create HDL Design File from Current File. Choose Verilog HDL or VHDL. Replace the original BDF module in the Quartus® Prime Pro Edition Software project with the generated HDL file. Explicitly reorder the bits in the top-level SystemVerilog HDL module by using a SystemVerilog HDL streaming operator in the port connection.Why do I get "Fatal Error: Access Violation at" when running quartus_syn or quartus_fit?

Additional Information Affected software: Quartus Prime Pro Edition Software version 26.1 and earlier Quartus Prime Standard Edition Software version 25.1 and earlierWhy does the Simulation Library Compiler fail due to a missing km_220model.sv file in Quartus® Prime Pro Edition 26.1?
Description Due to a problem in the Quartus® Prime Pro Edition Software version 26.1, the Simulation Library Compiler might fail when compiling simulation libraries for a supported third-party simulator (for example Aldec Riviera-PRO*, Siemens EDA QuestaSim*, or Cadence Xcelium*) if you compile libraries using RTL-only or Compatible Mode for Quartus simulation flow without selecting a specific device family. The compile might stop with an error that a simulation source file such as km_220model.sv cannot be found under the Quartus installation quartus/eda/sim_lib directory. Example errors: Cannot find source file: <Quartus installation>/quartus/eda/sim_lib/km_220model.sv Failed to open design unit file km_220model.sv in read mode. This occurs because the Simulation Library Compiler requests certain simulation model files that are not included in the Quartus® Prime Pro Edition software version 26.1 installer. Those model files are not required to simulate designs that target currently supported device families. Libraries that already compiled successfully before the error remain valid. Refer to the Quartus Prime Pro Edition User Guide: Third-party Simulation (document ID: 683870). Resolution To work around this problem in the Quartus® Prime Pro Edition Software version 26.1, follow these steps: Open a command prompt or terminal where the Quartus Prime software and your simulator license are available. Re-run the Simulation Library Compiler and specify your target device family with the -family option. Do not use an RTL-only compile that omits -family when you only need libraries for one device family. Example (Aldec Riviera-PRO, Verilog, Quartus-compatible mode): quartus_sh --simlib_comp -tool rivierapro -language verilog -mode quartus -family "Arria 10" -tool_path <path_to_riviera_bin> -directory <output_directory> Replace Arria® 10 FPGA with your device family name. Run quartus_sh --help=simlib_comp to list valid -family values for your install. Alternatively, in the Quartus Prime software GUI: Click Tools > Launch Simulation Library Compiler. Select your simulation tool, HDL language, target device family, and output location. Start Compilation. If you must keep an RTL-only or all-library compile on version 26.1 only: Create an empty placeholder file named km_220model.sv in <Quartus installation>/quartus/eda/sim_lib/. Re-run the Simulation Library Compiler. If the compile reports another missing file under sim_lib with a similar name pattern, create an empty placeholder for that file and continue. This problem is fixed in the Quartus® Prime Pro Edition Software version 26.3.Why does the DisplayPort example design fail to generate in Quartus® Prime Pro Edition Software version 26.1?
Description Due to a problem in Quartus® Prime Pro Edition Software version 26.1, you may see a software build failure when generating the DisplayPort FPGA IP Design Example. In this condition, the generated Nios® V software build fails in debug.c because the load_resolutions() call passes modes_found instead of &modes_found. You may see an error similar to the following: debug.c:486:94: error: passing argument 4 of 'load_resolutions' makes pointer from integer without a cast note: expected 'int *' but argument is of type 'int' Error: Failed to generate example design Resolution To work around this problem, modify debug.c line 486 either in the installed source or in the generated example design, and then regenerate or rebuild the design. Change: load_resolutions (1, mode_param_array, &dsc_data_pps_parameters, modes_found); to: load_resolutions (1, mode_param_array, &dsc_data_pps_parameters, &modes_found); This problem is scheduled to be resolved in a future release of the Quartus® Prime Pro Edition Software.Why is the Avalon MM interface optimized away when using the SDI Audio Embed or SDI Audio Extract IP?
Description Due to a problem in the Quartus® Prime Pro Edition Software version 25.3 and earlier, the SDI Audio Embed IP and SDI Audio Extract IP might show incorrect behaviour when the generated IP name is audio_embed or audio_extract. In this condition, the affected output ports are left undriven and connected to the default value gnd, you will see messages similar to those shown below: Output port "reg_waitrequest" in instance "u0" of entity "audio_extract" does not have a driver. Connecting to the default value "gnd". Output port "reg_readdatavalid" in instance "u0" of entity "audio_extract" does not have a driver. Connecting to the default value "gnd". Output port "reg_readdata[0..7]" in instance "u0" of entity "audio_extract" does not have a driver. Connecting to the default value "gnd". Output port "reg_waitrequest" in instance "u1" of entity "audio_embed" does not have a driver. Connecting to the default value "gnd". Output port "reg_readdatavalid" in instance "u1" of entity "audio_embed" does not have a driver. Connecting to the default value "gnd". Output port "reg_readdata[0..7]" in instance "u1" of entity "audio_embed" does not have a driver. Connecting to the default value "gnd". Resolution To work around this problem, use a different IP name to avoid a naming that conflicts with the generated HDL module naming used by the Quartus® Prime Pro Software for the SDI Audio Embed or SDI Audio Extract IP. For example: Do not name the SDI Audio Embed IP as audio_embed. Do not name the SDI Audio Extract IP as audio_extract. Regenerate the IP after renaming it to a non-conflicting name. This problem is currently scheduled to be resolved in a future release of the Quartus ® Prime Pro Edition Software.Why does the simulation of my Altera® AXI BFMs fail?
Description In the Quartus® Prime Pro Edition Software, a VHDL testbench generated by Visual Designer Studio or Platform Designer using Altera® AXI BFM will error out. The Altera AXI BFMs only support testbenches generated in Verilog HDL or System Verilog HDL. In the Siemens* Questa* Simulator, the error message may be similar to this: ** Error: <file name>.vhd: (vcom-1598) Library "<library name>" not found. Resolution To avoid this problem, generate the testbench in Verilog HDL or System Verilog HDL.Why Can't I Program Using Active Serial Programming with my USB Blaster III?
