Hello Jonathon Tried building the fractional downsampler from synchronous labs and have encountered the following error: source file was generated for simulation and is not permitted as input to synthesis [/home/snehasish/rfnoc-SynchronousLabs/rfnoc/fpga-src/fract_dec_filter.vhd:241995]
Can you please help me with it.

Your best bet is to try to use the one made by Synchronous Labs a few years ago. Their code is on github here: https://github.com/SynchronousLabs/rfnoc-SynchronousLabs. Since it was built, RFNoC has had some changes that will need to be fixed, but I think this is your only option versus writing one from scratch.

I am trying to divide 25 MHz spectrum into 124 subchannels each of bandwidth 200KHz. I am capturing the signal at 200msps and I need to decimate it to 25.6msps(25MHz/128 channels). Please help me in understanding how this can be achieved using RFNoC, is there’s any block already defined for fractional downsampling.
