Hi,


From the error it looks like it is not able to link Quartus IP library. Can you check your environment to see if the "QUARTUS_INSTALL_DIR" and "QUARTUS_LIB_DIR" is set correctly? Or do you have the Quartus license setup correctly?

    Hi John,

    QUARTUS_INSTALL_DIR and QUARTUS_LIB_DIR are set to Quartus' installation path from root:

     $ set | grep QUARTUS
    QUARTUS_INSTALL_DIR=/shared/opt/intel/intelFPGA_pro/22.4/quartus
    QUARTUS_LIB_DIR=/shared/opt/intel/intelFPGA_pro/22.4/quartus

    If I modify from these values, vcs_sim.sh fails in the compilation phase, as it cannot find the source files to compile.

    LM_LICENSE_FILE is pointing to:

    $ set | grep LM
    LM_LICENSE_FILE=4071@licmgr:27020@licmgr:/shared/opt/intel/licenses/LR-107633_License.dat

    4071@licmgr is for Avery, 27020@licmgr is for VCS and Verdi, and LR-107633_License.dat is for Quartus.

    Any other suggestion?

    Thank you,

    Ricardo.
