Why does my Cyclone® V Hard IP for PCI Express simulation get stuck at the L0 state when using Aldec Riviera-PRO or Aldec ActiveHDL?

Description

The Cyclone® V Hard IP for PCI Express simulation can get stuck in the L0 state because the encrypted simulation models are attempting to use a Quartus® II software define statement that is not included in the riviera_pro.tcl simulation script.

Resolution

Go into riviera_pro.tcl and update the following lines:

from:
  vlog "/eda/sim_lib/aldec/cyclonev_atoms_ncrypt.v"          -work cyclonev_ver
  vlog "/eda/sim_lib/aldec/cyclonev_hmi_atoms_ncrypt.v"      -work cyclonev_ver
  vlog "/eda/sim_lib/aldec/cyclonev_hssi_atoms_ncrypt.v"     -work cyclonev_hssi_ver
  vlog "/eda/sim_lib/aldec/cyclonev_pcie_hip_atoms_ncrypt.v" -work cyclonev_pcie_hip_ver

to:
  vlog define QUARTUS "/eda/sim_lib/aldec/cyclonev_atoms_ncrypt.v"          -work cyclonev_ver
  vlog define QUARTUS "/eda/sim_lib/aldec/cyclonev_hmi_atoms_ncrypt.v"      -work cyclonev_ver
  vlog define QUARTUS "/eda/sim_lib/aldec/cyclonev_hssi_atoms_ncrypt.v"     -work cyclonev_hssi_ver
  vlog define QUARTUS "/eda/sim_lib/aldec/cyclonev_pcie_hip_atoms_ncrypt.v" -work cyclonev_pcie_hip_ver

Any line that has ncrypt needs a defined QUARTUS added to it.

Run in the Aldec tool the following commands for successful simulation:
