Why does the R-Tile Avalon® Streaming Intel® FPGA IP for PCI Express fails in hardware when using the Intel® Quartus® Prime Pro Edition Software Programmer v21.4 and v22.1? - Why does the R-Tile Avalon® Streaming Intel® FPGA IP for PCI Express fails in hardware when using the Intel® Quartus® Prime Pro Edition Software Programmer v21.4 and v22.1? Description Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.4 and 22.1, you might experience functional problems in designs that include an instance of the R-Tile Avalon® Streaming Intel® FPGA IP for PCI Express. The functional problems only happen when loading a SRAM Object File (.sof) using an Intel® Quartus® Prime Software Programmer version that doesn't match with the Intel® Quartus® Prime Software version used to generate the .sof file. Use the following table as reference: Intel® Quartus® Prime Software Programmer version Intel® Quartus® Prime Pro Edition Software version Result 21.4 21.4 No functional problems 21.4 22.1 Potential functional problems 22.1 21.4 Potential functional problems 22.1 22.1 No functional problems Resolution To work around this problem, load the SRAM Object File (.sof) with the Intel® Quartus® Prime Software Programmer version that matches the Intel® Quartus® Prime Software version used to generate the .sof file Custom Fields values: ['novalue'] Troubleshooting 15011187934 False ['Interfaces'] ['FPGA Dev Tools Quartus® Prime Software Pro'] 22.3 21.4 ['Agilex™ 7 FPGA I-Series'] ['Quartus® Prime Pro Edition Programmer and Tools'] ['novalue'] ['novalue']
