User Guide

In addition, before you compile your system to generate an SRAM Object File (.sof)
with which to configure your device, Altera recommends that you create assignments
for the high-speed transceiver VCCH settings.

To create assignments for the high-speed transceiver VCCH settings, perform the
following steps:

1. In the Quartus II window, on the Assignments menu, click Assignment Editor.

2. In the <> cell in the To column, type the top-level signal name for your

CPRI IP core instance

gxb_txdataout

signal.

3. Double-click in the Assignment Name column and click I/O Standard.

4. Double-click in the Value column and click your standard (for example, 1.5-V

PCML)

.

5. In the new <> row, repeat steps

Compiling and Programming the Device

You can use the Start Compilation command on the Processing menu in the
Quartus II software to compile your design. After successfully compiling your design,
program the targeted Altera device with the Programmer and verify the design in
hardware.

Instantiating Multiple CPRI IP Cores

If you want to instantiate multiple CPRI IP cores in an Arria II, Cyclone IV GX, or
Stratix IV GX device, to ensure your design optimizes its use of device pins, you must
observe the following additional requirements:
