15.4.1. General Parameters for Arria V GZ Native PHY

This section describes the datapath parameters in the General Options tab for the Arria V GZ native PHY.

Table 251.  General and Datapath OptionsThe following table 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.
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 Intel® Quartus® Prime rules checker reports an error if you specify incompatible parameters. If you select the warning message level, the Intel® Quartus® Prime 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 or x1

Bonded or ×6/xN

fb_compensation

In Non-bonded or x1 mode, each channel is paired with a PLL.

If one PLL drives multiple channels, PLL merging is required. During compilation, the Intel® Quartus® Prime Fitter, merges all the PLLs that meet PLL merging requirements. Refer to Merging TX PLLs In Multiple Transceiver PHY Instances to observe PLL merging rules.

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 Arria V devices chapter of the Arria 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 Table 259 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.
