Constraints
To choose the constraints for your device, follow these steps:
1. Click Step 2: Constraints in IP Toolbench.
2. Choose the positions on the device for each of the DDR SDRAM byte groups. To
Set Up Simulation
An IP functional simulation model is a cycle-accurate VHDL or Verilog HDL model
produced by the Quartus II software. The model allows for fast functional simulation
of IP using industry-standard VHDL and Verilog HDL simulators.
To generate an IP functional simulation model for your MegaCore function, follow these steps:
1. Click Step 3: Set Up Simulation in IP Toolbench.
2. Turn on Generate Simulation Model.
3. Choose the language in the Language list.
4. Some third-party synthesis tools can use a netlist that contains only the structure
5. Click OK.
Generate
To generate your MegaCore function, follow these steps:
1. Click Step 4: Generate in IP Toolbench.

design that contains the MegaCore function. If your synthesis tool supports this
feature, turn on Generate netlist.

directory. The names and types of files specified in the IP Toolbench report vary
based on whether you created your design with VHDL or Verilog HDL.
You may only use these simulation model output files for simulation
purposes and expressly not for synthesis or any other purposes. Using these
models for synthesis will create a nonfunctional design.
The floorplan matches the orientation of the Quartus II floorplanner. The
layout represents the die as viewed from above. A byte group consists of
four or eight DQ pins, a DM pin, and a DQS pin.
IP Toolbench chooses the correct positions, if you are using an Altera board
preset.
To use the IP Toolbench-generated testbench, choose the same language
that you chose for your variation.
