Hello everyone for some weeks now i try to pass through the zedboard audio codec (ADAU1761) sound, initially i found a very useful tutorial at www.rtlaudiolab.com/.../ which i followed but without success. My intention and what i have done is implementing the same logic in VHDL, but something it is not working i tested the SystemVerilog code and it worked. I am not really sure what went wrong and if someone could loom over my code or point me into the right direction because i do not know what to do anymore especially that over the internet it seems that is a lack of resources about this topic(I also found the github repository of Microelectronic Systems Design Research Group, but they implement it over I2C which is not what i need.
Here is the WeTransfer link with both archives of systemverilog code and vhdl code that i tried, thank you in advance for reading my post and trying to help https://we.tl/t-4iSOKsY3nF
