Parameterized combinational logic shifter or barrel shifter megafunction. Altera recommends using the lpm_clshift function instead of any other type of shifter. The lpm_clshift megafunction is available for all Altera devices.
Altera recommends instantiating this function with the IP Catalog.
When you create your megafunction, you can use the IP Catalog to generate a netlist for third-party synthesis tools.
