6.13. Ports and Parameters
The reconfiguration interface is integrated in the Native PHY instance and the TX PLL
instances. Instantiate the Native PHY and the TX PLL IP cores in Qsys by clicking
Tools ➤ IP Catalog. You can define parameters for IP cores by using the IP core-
specific parameter editor. To expose the reconfiguration interface ports, select the
Enable dynamic reconfiguration option when parameterizing the IP core.
You can share the reconfiguration interface among all the channels by turning on
Share reconfiguration interface when parameterizing the IP core. When this option
is enabled, the IP core presents a single reconfiguration interface for dynamic
reconfiguration of all channels. Address bits [9:0] provide the register address in the
reconfiguration space of the selected channel. The remaining address bits of the
reconfiguration address specify the selected logical channel. For example, if there are
four channels in the Native PHY IP instance, reconfig_address[9:0] specifies the
address and reconfig_address[11:10] are binary encoded to specify the four
channels. For example, 2'b01 in reconfig_address[11:10] specifies logical
channel 1.
The following figure shows the signals available when the Native PHY IP core is
configured for four channels and the Share reconfiguration interface option is
enabled.

Table 191. Reconfiguration Interface Ports with Shared Native PHY Reconfiguration
Interface
The reconfiguration interface ports when Share reconfiguration interface is enabled. <N> represents the
number of channels.
Port Name
Direction Clock Domain Description
reconfig_clk
Input N/A Avalon clock. The clock frequency is 100-125
MHz.
reconfig_reset
Input
reconfig_clk
Resets the Avalon interface. Asynchronous to
assertion and synchronous to deassertion.
reconfig_write
Input
reconfig_clk
Write enable signal. Signal is active high.
reconfig_read
Input
reconfig_clk
Read enable signal. Signal is active high.
reconfig_address[log2<N>+9:0]
Input
reconfig_clk
Address bus. The lower 10 bits specify address
and the upper bits specify the channel.
