I2S Interface

Hello Gedro,

I have a question regarding i2s_interface on opencores. I am a newbie and I need to have an i2s interface between my FPGA(Zynq 7) and Audio Codec. So i took the i2s interface from opencores.org and i created a project in Vivado 2018.3 and added design files and simulation file. I have couple some questions:

1. seems like that my top does not communicate with "gen_control_reg" or it is not in the library because what i see here under design sources beside gen_control_reg is a question mark xil_defaultlib.gen_control_reg

2. In the testbench we use work.wb_tb_pack.all So I added the wb_tb_pack to design sources but when I check in libraries , wb_tb_pack.vhd is a part of Unreferenced files . What should I do?

P.S. I tried to send you an email but your email address did not work so I had to post here.

Bests, Mana
