ncelab: *E,USMSLC (../submodules/sequencer_scc_mgr.sv,321|24): Unsupported memory slice specification using part select or indexed part select.

Description

When simulating the UniPHY-based DDR3 SDRAM controller with NC-Sim version 9.2 or earlier, the following error might occur:

ncelab: *E,USMSLC (../submodules/sequencer_scc_mgr.sv,321|24): Unsupported memory slice specification using part select or indexed part select.
   assign setting_masks [1:9] = '{ 'b01111, 'b01111, 'b01111, 'b11111, 'b01111, 'b00111, 'b01111, 'b00111, 'b01111 };

ncelab: *E,USMSLC (../submodules/sequencer_scc_mgr.sv,322|22): Unsupported memory slice specification using part select or indexed part select.
  assign afi_addr = {AFI_RATIO{ {(MEM_ADDRESS_WIDTH-13){1'b0}}, ac_bus[12:0] }};

Resolution

To work around this problem, use NC-Sim version 10.2 or later version.
