2.1.6.3. Simplex Channel Merging
You can merge the following logical instances into a single physical channel:
- RX-only PHY and TX-only PHY instances (RX-only GXT and TX-only GX PHY instances cannot be merged into the same physical channel location.)
- CMU PLL and TX-only PHY instances
Figure 32. Simple Channel Merging: RX-only PHY and TX-only PHY
Figure 33. Channel Merging: CMU PLL and TX-only PHY instances
Rules for Merging
- Reconfiguration interface (reconfig_*) of both instances to be merged must be driven by the same source.
- QSF assignments are needed to specify which two reconfiguration interfaces you want to merge.
- Option 1: Using reconfiguration interface names
-
set_instance_assignment -name XCVR_RECONFIG_GROUP 0 -to topdesign:topdesign_inst|<TX only instance name>*ct1_hssi_avmm1_if_inst->inst_ct1_xcvr_avmm1
-
set_instance_assignment -name XCVR_RECONFIG_GROUP 0 -to topdesign:topdesign_inst|<RX only instance name>*ct1_hssi_avmm1_if_inst->inst_ct1_xcvr_avmm1
-
- Option 2: Using pin names
- set_instance_assignment -name XCVR_RECONFIG_GROUP 0 –to tx[0]
- set_instance_assignment -name XCVR_RECONFIG_GROUP 0 –to rx[0]
- Option 1: Using reconfiguration interface names
- The simplex channels cannot be merged if any of the following options are enabled in one or both simplex instances:
- Native PHY Debug Master Endpoint (NPDME)
- Optional reconfiguration logic
- Embedded reconfiguration streamer
- Shared reconfiguration interface
