Simulate the

Example Design

This section describes the following simulation techniques:

■ Simulate with IP Functional Simulation Models

■ Simulating in Third-Party Simulation Tools Using NativeLink

Simulate with IP Functional Simulation Models

You can simulate the example design using the IP Toolbench-generated IP

functional simulation models. IP Toolbench generates a VHDL or Verilog

HDL testbench for your example design, which is in the testbench

directory in your project directory.

f For more information on the testbench, refer to “Example Design” on

page 2–14.

You can use the IP functional simulation model with any

Altera-supported VHDL or Verilog HDL simulator. To simulate the

example design with the ModelSim

simulator, follow these steps:

1. Obtain a memory model that matches your chosen parameters and

save it to the <directory name>\testbench directory. For example,

you can download a RLDRAM II model from the Micron web site at

www.micron.com.

1 Before running the simulation you may also need to edit the

testbench to match the chosen RLDRAM II model.

2. Start the ModelSim-Altera simulator.

3. Change your working directory to your IP Toolbench-generated file

directory <directory name>\testbench\modelsim.

4. To simulate with an IP functional simulation model simulation, type

the following command:

source <variation name>_vsim.tcl

1 Before running the simulation, you may have to edit the

set memory model parameter in the <variation

name>_vsim.tcl file to match the selected RLDRAM II

model.

5. For a gate-level timing simulation (VHDL or Verilog HDL

ModelSim output from the Quartus II software), type the following

commands:

set use_gate_model 1
