AR# 12673: 4.1i CORE Generator - Single Port Block Memory v4_0, the EDIF file generated is incomplete when "Limit Data Pitch" option and "Select Primitive" are used
ERROR:Pack:198 - NCD was not produced. All logic was removed from design. This is usually due to having no input or output PAD connections in the design and no nets or symbols marked as 'SAVE'. You can either add PADs or 'SAVE' attributes to the design, or run 'map -u' to disable logic trimming in the mapper. Problem encountered generating the NCD. Mapping completed. See MAP report file "top.mrp" for details.
