Filter FIR on FPGA

GNU Radio
1

Hi,
I’m designing a pass band filter FIR on FPGA. This filter has 64MHz of
sample
rate and as window type “HAMMING”. I’m using “MegaCore® IP Library” for
design
of the filter.
Is correct to use this software for design of the filter? Could you
suggest me
other software for design of filter?

Thank you very much.

Design it by hand.
I allways do it like that, you have better control of what resources are
used for the filter.
(Especially when using an FPGA without multipliers like the Cyclone)
And you can use the filter on any FPGA and share the code with people
who do not have access to MegaCore® IP Library.

If you only need the filter-taps, you can use the firdes or optfir (part
of gnuradio, see gnuradio-examples on how to use)
