General Parameters
Table 12–2 lists the parameters available on the General Options tab. Note that you
can enable the Standard PCS, the 10G PCS, or both if you intend to reconfigure
between the two available PCS datapaths.
Table 12–2. General and Datapath Options
Name Range Description
Device speed grade fastest–3_H3 Specifies the speed grade.
Message level for rule violations
error
warning
When you select the error message level, the Quartus II rules
checker reports an error if you specify incompatible parameters.
If you select the warning message level, the Quartus II rules
checker reports a warning instead of an error.
Datapath Options
Enable TX datapath On/Off When you turn this option On, the core includes the TX datapath.
Enable RX datapath On/Off When you turn this option On, the core includes the RX datapath.
Enable Standard PCS On/Off
When you turn this option On, the core includes the Standard
PCS. You can enable both the Standard and 10G PCS if you plan
to dynamically reconfigure the Native PHY.
Enable 10G PCS On/Off
When you turn this option On, the core includes the 10G PCS.
You can enable both the Standard and 10G PCS if you plan to
dynamically reconfigure the Native PHY.
Number of data channels Device Dependent
Specifies the total number of data channels in each direction.
From 1–32 channels are supported.
Bonding mode
Non–bonded
×6
fb_co
mpensation
In Non–bonded mode, each channel is paired with a PLL. During
Quartus II compilation, the Fitter merges all PLLs that meet
merging requirements into a single PLL.
Select ×6 to use the same clock source for up to 6 channels in a
single transceiver bank, resulting in reduced clock skew. You
must use contiguous channels when you select ×6 bonding. In
addition, you must place logical channel 0 in either physical
channel 1 or 4. Physical channels 1 and 4 are indirect drivers of
the ×6 clock network.
Select fb_compensation (feedback compensation) to use the
same clock source for multiple channels across different
transceiver banks to reduce clock skew.
For more information about bonding, refer to “Bonded Channel
Configurations Using the PLL Feedback Compensation Path” in
Transceiver Clocking in Stratix V Devices in volume 2 of the
Stratix V Device Handbook.
Enable simplified data interface On/Off
When you turn this option On, the Native PHY presents only the
relevant data bits. When you turn this option Off, the Native PHY
presents the full raw interface to the fabric. If you plan to
dynamically reconfigure the Native PHY, you must turn this
option Off and you need to understand the mapping of data to the
FPGA fabric. Refer to “Active Bits for Each Fabric Interface Width”
for more information. When you turn this option On, the Native
PHY presents an interface that includes only the data necessary
for the single configuration specified.
