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
