Decipher Algorithm from Verilog source code

Hi, strange as it may seem to ask, I need a tool/program/online resource 
that can convert a verilog file into an algorithm.

All the searches I have made only teach how to implement an algorithm in 
verilog but not the reverse.

Please help with advice and/or links to software/online tools where I 
can upload a verilog file and decipher the underlying algorithm.

Thanks.
