Ask HN: Requesting a Schematic reviewithpointers for an SDR I am trying to build

Hi, I am trying to modify the HackRf (https://greatscottgadgets.com/hackrf) by removing the cpld and putting an Artix-7 (xc7a35t) for baseband dsp processing. I am a complete noob at this, could some take a look at the schematics and tell me if I am doing it right? I have posted the project in it's current state on Github: https://github.com/ainnovators/noob-sdr

The FPGA connections are referenced from Cmod A7 by Digilent.
