Why does the DSP IP fail to simulate using the Intel Quartus Prime Software bundled in Intel® Acceleration Stack Version 1.2.1? - Why does the DSP IP fail to simulate using the Intel Quartus Prime Software bundled in Intel® Acceleration Stack Version 1.2.1? Description 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/fp_add_dsp_altera_fpdsp_block_191_m5cimji.sv(30): 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. Resolution To work around this problem in the Intel® Acceleration Stack Version 1.2.1, follow these steps: Refer to the latest Makefile. https://github.com/OPAE/opae-sim/tree/master/ase/Makefile Makefile is generated by executing afu_sim_setup commands in your design and you must customize it. Go to the Download Center for FPGAs and install the Intel® Quartus® Prime Pro Edition Software with the specific version that you are using. Go to the <Quartus Installation Path>/ quartus/eda directory and find the sim_lib simulation library folder. 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.
