Due to a problem in the R-Tile Avalon® Streaming Intel® FPGA IP for PCI Express*, you may observe an error message saying the simulation stopped due to inactivity when using the Synopsys* VCS*/VCS MX* simulator.
To work around this problem, when starting the simulation, execute the following command:
sh vcs_setup.sh USER_DEFINED_COMPILE_OPTIONS="" USER_DEFINED_ELAB_OPTIONS="-xlrm\ uniq_prior_final\ -debug_access+all" USER_DEFINED_SIM_OPTIONS="" TOP_LEVEL_NAME="pcie_ed_tb" | tee simulation.log
This problem is fixed in version 22.3 of the Intel® Quartus® Prime Pro Edition Software.
