Why does the DSP IP fail to simulate using the Intel Quartus Prime Software bundled in Intel® Acceleration Stack Version 1.2.1?


  • Intel® Quartus® Prime Pro Edition
  • DSP
  • Intel® Acceleration Stack for Intel® PAC with Arria® 10 GX - Development IAS-Arria10GX-Development

    Due to a problem of linking to simulation library files in Intel® Acceleration Stack Version 1.2.1,  the following error messages may occur when trying to simulate a design with digital signal processing (DSP) intellectual property (IP):

    # ** Error: <root_directory>/s_kpoc_rtl/quartus_fp_dsp/fp_add_dsp/altera_fpdsp_block_191/sim/ Module 'twentynm_fp_mac' is not defined.

    # ** Error: (vlog-13069) <Quartus Installation Path>/quartus/eda/sim_lib/twentynm_atoms.v(1): near "/": syntax error, unexpected '/', expecting class.


    To work around this problem in the Intel® Acceleration Stack Version 1.2.1, follow these steps:

    1. Refer to the latest Makefile.
      Makefile is generated by executing afu_sim_setup commands in your design and you must customize it.
    2. Go to the Download Center for FPGAs and install the Intel® Quartus® Prime Pro Edition Software with the specific version that you are using.

    3. Go to the <Quartus Installation Path>/ quartus/eda directory and find the sim_lib simulation library folder.

    4. Copy the sim_lib folder and replace the sim_lib simulation library folder found in the Intel® Acceleration Stack <Quartus Installation Path>/quartus/eda directory.

    Additional information

    This problem is scheduled to be fixed in a future patch release.
