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_clk, reconfig_reset, reconfig_write, reconfig_read, reconfig_address,
and reconfig_writedata ports of the two interfaces to be merged must be driven 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 analog parameter 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.
You cannot merge the TX and RX channels when the Shared reconfiguration interface parameter is
enabled in the Native PHY IP core Parameter Editor. You can merge channels only if the reconfiguration
interfaces are independent.
Example 6-2: Using reconfiguration interface names
This example shows how to merge a transmit-only Native PHY instance with a receive-only
instance using the reconfiguration interface names. These instances are assigned to reconfigura‐
tion group 0.
For Native PHY 0—transmit-only instance:
set_instance_assignment -name XCVR_RECONFIG_GROUP 0 -to
topdesign:topdesign_inst|<TX only instance name>*twentynm_hssi_avmm_if_inst*
