14. IP Toolbench uses a prefix (e.g., qdrii_ ) for the names of all memory
interface pins. Enter a prefix for all memory interface pins
associated with this custom variation.
15. Click Finish .
Step 2: Constraints
To choose the constraints for your device, follow these steps:
1.
2.
Click Step 2: Constraints in IP Toolbench.
Choose the positions on the device for each of the QDRII SRAM
byte groups. To place a byte group, select the byte group in the
drop-down box at your chosen position.

The floorplan matches the orientation of the Quartus II
floorplanner. The layout represents the die as viewed from
above. A byte group consists of a cq pin and a number of q
pins (the same number as the data width).
Step 3: 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.
