The two ways you can instantiate multiple transceiver channels in the General screen
of the ALTGX MegaWizard Plug-In Manager are:
■
■
When you create instances using the above methods, you can force the placement of
up to four transceiver channels within the same transceiver block. Do this by
assigning the tx_dataout and rx_datain ports of the channel instances to a single
transceiver bank. If you do not assign pins to the tx_dataout and rx_datain ports, the
Quartus II software chooses default pin assignments. When you compile the design,
the Quartus II software combines multiple channel instances within the same
transceiver block if the instances meet specific requirements. The following sections
explain these requirements for different transceiver configurations.
When you create multiple ALTGX instances, the Quartus II software requires that you
to set identical values for the following parameters and signals to combine the ALTGX
instances within the same transceiver block or in transceiver blocks on the same side
of the device. The following sections describe these requirements.
The Stratix IV GX device provides you the option to select 1.4 V or 1.5 V for the V
supply through the ALTGX MegaWizard Plug-In Manager. The Stratix IV GT device
only allows 1.4 V for the V
same transceiver block, the Quartus II software requires that you to set the same V
value in all the channel instances.
The data rate of the transmitter channel is limited based on the V
For the data rate restrictions, refer to the
Devices
The Stratix IV GX and GT device contains two different power supply pins, VCCA_L
and VCCA_R that provide power to the PMA blocks in all the transceiver channels on
the left and right sides of the device, respectively.
In the What is the number of channels? option, select the required value. This
method creates all the transceiver channels with identical configurations. For an
example, refer to
Blocks” on page
In the What is the number of channels? option, select 1 and create a single
channel transceiver instance. To instantiate additional transceiver channels with
an identical configuration, select the created ALTGX instance multiple times. If
you need additional transceiver channels with different configurations, create
separate ALTGX megafunction instances with different settings and use them in
your design.
