I have implemented a number of different CIC filters over the years. If the CIC Filter Megacore does not cover your requirements my recommendation is to implement it with Matlab/Simulink and the Altera DSP Builder.

There are a number of parameters like input and output bit width, number of stages, decimation/interpolation rate that influence the internal bit width of each stage which makes it hard to code a generic CIC filter in plain HDL.
