Cannot merge HSSI Avalon Memory-Mapped interface instances for simplex JESD designs

When instantiating simplex Rx and Tx JESD cores generated by quartus, and enabling the reconfiguration interfaces, the following placement error shows:

Error (12829): Failed to merge HSSI Avalon Memory-Mapped interface instances "main|devices[0].jesd204_rx_core|main|intel_arria_10.unit|intel_jesd204_core|jesd204_core|jesd204_0|inst_phy|inst_xcvr|g_xcvr_native_insts[1].twentynm_xcvr_native_inst|twentynm_xcvr_native_inst|inst_twentynm_xcvr_avmm|avmm_atom_insts[0].twentynm_hssi_avmm_if_inst" and "main|devices[0].jesd204_tx_core|main|intel_arria_10.unit|intel_jesd204_core|jesd204_core|jesd204_0|inst_phy|inst_xcvr|g_xcvr_native_insts[1].twentynm_xcvr_native_inst|twentynm_xcvr_native_inst|inst_twentynm_xcvr_avmm|avmm_atom_insts[0].twentynm_hssi_avmm_if_inst" into single Avalon Memory-Mapped Interface.

 

The error is also described here, albeit for a different IP, but still the error is the same..

Another similar issue is here, which does seem to have a workaround

So is there a workaround for my case as well, or is upgrading to latest quartus really necessary, and how do I know that this will in fact solve the issue?

Without having to upgrade my entire design to the latest quartus

Hello cheyert

Thank you for posting on the Intel® communities.


We noticed that you have another thread in the Programmable Devices Forum regarding the same inquiry where we are already assisting you.

In this case, we will close this one to avoid duplication of efforts, and the support will continue through the other thread >> https://community.intel.com/t5/Programmable-Devices/Cannot-merge-HSSI-Avalon-Memory-Mapped-interface...
