You can use the Aldec Riviera-PRO software to perform a post-synthesis simulation of a VHDL or Verilog HDL design that contains Altera-specific components.
For details about how to perform a post-synthesis simulation with the Riviera-PRO GUI, refer to the Riviera-PRO documentation from Aldec, Inc.
To continue with the Riviera-PRO simulation flow, perform a gate-level simulation with the Riviera-PRO software.
