Cyclone V E Uniphy Controller Error 174077

Hello All, I am working with a Cyclone V E development board and I'm having a problem creating the uniphy hard memory controller.

I instantiated the uniphy hard memory controller in Qsys and the system completes synthesis but during fitting I get the following error. I cannot find any information on this error and I am at a loss as to how to resolve it. Any help is appreciated. Thanks! Error (174077): On-chip termination control block "ddr3_test1:ddr1|ddr3_test1_mem_if_ddr3_emif_0:mem_if_ddr3_emif_0|altera_mem_if_oct_cyclonev:oct0|sd1a_0" is associated with conflicting I/Os.

Thank you, I did run the script. The error occurred after running the script.

Any idea which assignments might be wrong?For more complete information about compiler optimizations, see our Optimization Notice.
