Obtain code coverage info

I am running my application on FPGA and I want to have code coverage report.
I am able to know for each opcode in FPGA memory if it has been read or not and from this know the global code coverage and also per function when using the function addresses from the .ORC file.
I would like to have a better view of which code is executed/not executed in each function.
For this I need information correlating hex and src.
There should be a way to obtain this from the tool-set since the simulator is offering such coverage function.
Thanks in advance for your help.
