Stratix II GX Post-Fit Timing Simulation Design Example with ModelSim-Altera (VHDL)
This VHDL design example shows how to perform gate-level timing simulations of your design implemented in Altera® Stratix® II GX devices with the Mentor Graphics® ModelSim®-Altera simulator.
The design is created in VHDL and consists of a top-level module (multiplier block), an altpll megafunction, an lpm_mult megafunction, an altsynram megafunction, an alt2xgxb megafunction, and a testbench. The results of the multiplier are stored in the RAM and then later sent out through the GX transceiver and looped back to its own receiver.
Note: This example was developed using Quartus® II 7.1 SP1 design software running on a Windows XP SP2 machine and Mentor Graphics ModelSim-Altera 6.1g version running on the same host.

Using This Design Example
- Unarchive the attached file to your desired location.
- Invoke the Quartus II software and load the alt2gxb_example.qpf project.
- On the Assignments menu, click EDA Tool Settings to open the Settings dialog box and then click Simulation. Verify that ModelSim-Altera is selected in the Tool name field.
- On the Quartus II software toolbar, click compile. After compilation, the Quartus II software generates a post-fit netlist named alt2gxb_example.vho (for use with the ModelSim-Altera simulator tool) in <project_dir>/simulation/modelsim. The SDF Output File (alt2gxb_example .sdo), for annotating the delays in the gate-level timing simulation file, is also generated at the same location.
- Tor run ModelSim-Altera software, Invoke the ModelSim-Altera software.
- Change the directory name to <project_dir>/simulation/modelsim.
- To run the <project_dir>/simulation/modelsim/multiplier_run_msim_gate_vhdl.do script, type do –alt2gxb_example_run_msim_gate_vhdl.do in the ModelSim-Altera simulator console window.
For more information on using the Mentor Graphics ModelSim simulator tool, refer to Mentor Graphics ModelSim software documentation and the Mentor Graphics ModelSim Support chapter in volume 3 of the Quartus II Development Software Handbook.
