To combine or concatenate bus signals of varying widths, use the Concat IP. The Number of Ports defines the number of source signals that need to be concatenated together. Each of source can be of different width, as automatically determined by IP integrator or user-specified, as shown in the following figure. The resulting output is a bus that combines the source signals together. See the LogiCORE IP Concat Product Brief (PB041) for more information.
