Source FILE not found error-PCIE MCDMA Example design VCS simuation - Source FILE not found error-PCIE MCDMA Example design VCS simuation Hi team, I am using Quartus20.3 tool to generate example design for PCIe_MCDMA gen3x16. After generated,i go to the "project_name/pcie_ed_tb/pcie_ed_tb/sim/synopsis/vcs" path and set VCS_HOME for VCS-P2019.06-SP4. While i run the vcs_setup.sh, facing the source file not able to open for reading. Its shows that inside the path /tools/intel/intelfpga/20.3/quartus/eda/sim_lib/synopsis/ct1_hssi_atoms_ncrypt.sv File was not there. Kindly check the below error message and help to resolve this issue.

Maybe you should try to re-install or give it a try on another Quartus version. I also tried to run the simulation and it is successful.
