To rip bits out of a bus signal, use the Slice IP. The Din Width field specifies the width of the input bus, and Din From and Din Down To fields specify the range of bits to rip out. The output width, Dout Width, is automatically determined. See the LogiCORE IP Slice Product Brief (PB042) for more information.

Tip: You can use multiple Slice IP
to pull different widths of bits from the same bus net.
