Why does the R-tile Avalon® Streaming Intel® FPGA IP for PCI Express* respond with Configuration Request Retry Status (CRS) for physical function 7 (PF7) when the pX_app_req_retry_en_i[6] signal for physical function 6 (PF6) is asserted?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.3 and earlier, asserting the pX_app_req_retry_en_i[6] signal affects both physical function 6 (PF6) and physical function 7 (PF7) in the R-tile Avalon® Streaming Intel® FPGA IP for PCI Express*, causing the intellectual property (IP) to respond with Configuration Request Retry Status (CRS) for either physical function. This applies when the IP is in configuration mode 0 (1x16).

Resolution

This problem is fixed in the 22.4 release of the Intel® Quartus® Prime Pro Edition Software.
