Multi-cast Write Control Not Supported - Multi-cast Write Control Not Supported Description For designs created with version 11.0 or later of the high-performance controller II (HPC II), if you enable the Multi-cast write control option, the design will fail in simulation. Resolution The workaround for this issue is to add the MULTICAST_WR_EN parameter to the dut.v wrapper file that instantiates the controller wrapper ( alt_mem_if_ddr*_controller_top.sv ), so that MULTICAST_WR_EN is passed down to the controller wrapper.
