lpm_decode Altera® IP

Parameterized decoder Altera® IP. Altera recommends using lpm_decode for data input widths less than or equal to 8. In addition, if the project uses only a few sparse outputs of the decoder, Altera recommends using the lpm_compare Altera® IP with one input set to a fixed value, instead of the lpm_decode Altera® IP. The lpm_decode Altera® IP is available for all Altera devices.

Note: The lpm_shiftreg function is only supported for Arria® 10 and older device families.

Altera recommends instantiating this function with the IP Catalog.
