How to design a Hamming74 Decoder for FPGA using Verilog

Design a Hamming74 Decoder for FPGA using Verilog HDL and Modelsim!

This Verilog Hamming74 and Hamming84 decoder Verilog project is synthesizable for FPGA and ASIC.
The video also contains a testbench simulated using Modelsim Intel FPGA Edition.

In the testbench you understand how Hamming74 codewords are decoded and how 1bit errors are fixed, and 2bit errors are detected.

I didn't understand how can you point where the two bit error occurred?.That's the issue
