Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.3, the error message above may be seen while executing quartus_ipgenerate on a project with more than one R-tile Avalon® Streaming Intel® FPGA IP for PCI Express* instances.
Multiple error messages as the one below may also be seen as a result of the problem.
Error: Could not generate simulation scripts
Error: ram_txapp2x256: rpcie_ram_txapp2x256 does not support generation for Verilog Simulation. Generation is available for: Quartus Synthesis.
Error: qsys-generate failed with exit code 1: 1 Error, 0 Warnings
Error: SPD file was not generated: /nfs/disks/quartus_project/ip/rpcie/rpcie_ram_txapp2x256/rpcie_ram_txapp2x256.spd
To work around this problem, execute IP Generation from the Intel® Quartus® Prime graphic interface or generate the R-tile Avalon® Streaming Intel® FPGA IP for PCI Express* files individually using qsys-generate.
This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software v21.4.
