FIR filter does not build but is implemented

Dear miss/mister, I am an engineering student that just started to use Quartus prime in my internship. I am working on the bladeRF SDR(Software definded Radio) and I am implementing blocks to do s...

    Hi,


    Please see the technology Map viewer as well. It seems there is no issue with the IP or build or resource estimation.


    Can you please try with the simulation block by block and provide a sufficient input value to the filter, so that after multiplication with the coefficients it should not be very low value, at least you should get a signal in the +/-1 range. You definitely need to do scaling.


    Thank you

    Hi,

    First of all thank you for your answer.

    I looked at the technology Map viewer everything seems to be implemented correctly. I now managed to have more DSP blocks used when building the project. Do you mean with "scaling" whether to truncate or saturate the output ?

    I still have an issue I have nothing at the output when I test the implementation. Is it possible to simulate only certain blocks (like the fir filter) in my whole project instead of the whole project?

    I am adapting the BladeRF project which has a lot of blocks but I only want to simulate the blocks I added to that project and implemented myself. Also I have Quartus Prime Lite Edition. Can I simulate with it for free or do i need a license for simulations ?

    Thank you in advance.

    Kind regards,
