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.
If your design is not part of a Quartus II project, it is a standalone design. Before
compiling your standalone design in the Quartus II software, you must assign CPRI
I/O signals to virtual pins.
If you want to instantiate multiple CPRI MegaCore functions, you must complete a
few additional steps. When your design contains multiple MegaCore functions, you
must ensure that the gxb_cal_blk_clk input and gxb_powerdown signals are
connected properly, and that the instances each have different starting channel
numbers.
You must ensure that the gxb_cal_blk_clk input to each CPRI MegaCore function (or
any other megafunction or user logic that uses the ALTGX megafunction) is driven by
the same calibration clock source.
When you merge multiple CPRI MegaCore functions in a single transceiver block, the
same signal must drive gxb_powerdown to each of the CPRI MegaCore function
variations and other megafunctions, MegaCore functions, and user logic that use the
ALTGX megafunction.
Multiple CPRI MegaCore functions in a single device must use distinct transceiver
channels. You enforce this restriction by specifying different starting channel numbers
for the distinct CPRI MegaCore functions. The starting channel number is a parameter
whose value you specify for each CPRI MegaCore function in the CPRI parameter
editor. Refer to
