Description
Due to a problem in the Quartus® Prime Pro Edition Software version 18.1 update 1 and earlier, IP files for both varieties are generated irrespective of the selected architecture (hybrid or parallel). As a result, both the high speed and low speed Viterbi Decoder licenses will be required for IP compilation.
Resolution
To work around this problem, edit the .qip file by deleting the HDL and .ocp files for IP varient not intended to use.
