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 |
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
