Configuring DRAM with FPGA Memory Items

Use the FPGA memory item interface to use DRAM in the same way that you use block memory and look-up tables (LUT). DRAM memory items appear in the Project Explorer window under the FPGA target. The FPGA memory item interface allows you to partition the physical DRAM banks into multiple memory items.

Complete the following steps to configure DRAM with FPGA memory items.
  1. To create a target-scoped memory item, right-click the FPGA target in the Project Explorer window and select New » Memory from the shortcut menu.

    The Memory Properties dialog box appears.

  2. Select DRAM from the Implementation pull-down menu.
  3. Select the DRAM bank you want to use from the DRAM bank pull-down menu.
  4. Type in the number of elements based upon your desired memory size in the Requested number of elements textbox.
  5. Click OK in the Memory Properties dialog box.

    The memory item is now populated in the Project Explorer window under the target.

  6. Use the memory item in an FPGA VI.
