Error: Failed to generate example design example_design to:

The error "Error: Failed to generate example design example_design to:" will be observed when generating the R-Tile Avalon® Streaming Intel® FPGA IP for PCI Express* Design Example using the Intel® Quartus® Prime Pro Edition Software version 22.1.

The error is caused by attempting to generate the design example with the Example Design Files "Synthesis" option enabled, but the "Simulation" option is not enabled.

To work around this problem, ensure that both Simulation and Synthesis options are enabled before clicking the "Generate Example Design" button.

This problem has been fixed starting in version 22.3 of the Intel® Quartus® Prime Pro Edition Software.
