Directory Structure :

1. 5gnr_opensource/build/ : contains files required to compile the code
   a. common : contains individual module's makefile
   b. config : contains SSI memory configuration
   c. odu    : contains main makefile to generate an executable binary
	
2. 5gnr_opensource/src/ : contains layer specific source code
   a. 5gnrmac  : MAC source code
   b.	5gnrrlc  : RLC source code
   c. cm       : common, environment and interface files
   d. cu_stub  : Stub code for CU
   e. du_app   : DU application and F1 code 
   f. mt       : wrapper functions over OS
   g. phy_stub : Stub code for Physical layer
   h. rlog     : logging module


Pre-requisite for Compilation :
1. Linux 32-bit/64-bit machine
2. GCC version 4.6.3 and above

How to Compile:
1. cd 5gnr_opensource/build/odu
2. To clean and compile: 
    a. DU : make clean_all odu  MACHINE=BIT64 TEXT_LOG=YES MODE=FDD
    b. CU : make clean_cu cu_stub MACHINE=BIT64 TEXT_LOG=YES MODE=FDD 

How to execute:
1. DU :
    a. cd 5gnr_opensource/build/odu/bin/odu
    b. ./odu -f ../config/ssi_mem
2. CU :
    a. cd 5gnr_opensource/build/odu/bin/cu_stub
    b. ./cu_stub -f ../config/ssi_mem
