The following example shows one Native PHY IP instance of a TX-only channel and an
instance of a CMU PLL.

Rules for Merging Reconfiguration Interfaces Across Multiple IP Cores
To merge reconfiguration interfaces across multiple IP blocks, you must follow these
rules:
1. The control signals for the reconfiguration interfaces of the IP blocks must be
driven by the same source. The
reconfig_write
reconfig_writedata
from the same source.
2. You must make a QSF assignment to manually specify which two reconfiguration
interfaces are to be merged.
a. Use the XCVR_RECONFIG_GROUP assignment.
b. Set the To field of the assignment to either the reconfiguration interfaces of
the instances to be merged or to the pin names. The reconfiguration interface
has the string twentynm_hssi_avmm_if_inst.
c. Assign the two instances to be merged to the same reconfiguration group.
You cannot merge multiple reconfiguration interfaces when ADME, optional
reconfiguration logic, or embedded reconfiguration streamer are enabled in the Native
PHY IP core.
