Why does the design example generation fail when upgrading from Intel® Quartus® Prime Software v21.3 and earlier to v21.4 of the P-Tile Avalon® Streaming Intel® FPGA IP for PCI Express?

Description

Due to a known problem, the P-Tile Avalon® Streaming Intel® FPGA IP for PCI Express design example generation will fail if the base IP has been upgraded from Intel® Quartus® Quartus Prime Software v21.3 and earlier to v1.4.

Resolution

When using version 21.4 of the Intel® Quartus® Prime Pro Edition Software, a clean non-upgraded version of the P-Tile Avalon® Streaming Intel® FPGA IP for PCI Express IP must be used.

This problem has been fixed starting with the 22.1 version of the Intel® Quartus® Prime Pro Edition Software.
