Error: (vopt-3373) Range of part-select [3:4] into 'data_out' [3:0] is reversed

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 22.3 and earlier, you might see the following error message during the PHY Lite for Parallel Interfaces IP example design simulation with the pin width set to 4.

Error: ../../ip/ed_sim/ed_sim_mem_0/altera_phylite_agent_191/sim/phylite_agent.sv(260): (vopt-3373) Range of part-select [3:4] into 'data_out' [3:0] is reversed.

# ** Error (suppressible): ../../ip/ed_sim/ed_sim_mem_0/altera_phylite_agent_191/sim/phylite_agent.sv(260): (vopt-2957) LSB 4 of part-select into 'data_out' is out of bounds.

Resolution

Currently, no workaround exists for this problem. Pin widths of 4 or less show this problem, but pin widths of 5 will work.
