### Included Fixes: ###
- Ease of use of gprof and address sanitizer for debugging purposes
- Updated json files to allow for GDB, real-time debugging capabilities
- Updated logging features to minimally log only key connection milestones. This imroves scalability of multiple UEs.
- Updated logging to include time stamp for timing analysis
- Updated memory allocation procedures to correct size requirements
- Added debugging features to handle signal terminations
- nfapi.c pullarray8 fix invalid pointer math
- Overlapping destination and source memory in memcpy, so updated to memmove to check for this bug
- Advanced error checking mechanisms in critical pack and unpack functions
- Created option for CPU assignment to UE to improve scalability
- Added EPC integration to allow multiple individual UE entities to each have their USIM information parced by the executables
- Updated random value seeds to minimize probability of error in generation of random values
- Enables capability round robin scheduler if desired
- Enables capability real time scheduler if desired
- Added new standalone functions to the UE phy-layer (phy_stub_ue.c) to incorporate individual UE entities
- Updated sending and packing functions in UE (lte_ue.c) to incorporate new standalone changes
- Incorporated semaphores to control timing of incoming downlink packets
- Implemented new queuing system to handle message exchange from UE to eNB and vice versa
- Updated global value in nFAPI for size of subframe
- Updated global value to increase scalability in system

This simulator connects a eNodeB and UEs through a nfapi interface, short-cutting the L1 layer. The objective of this simulator is to allow multi UEs simulation, with a large number of UEs (ideally up to 255 ) .Here to ease the platform setup, UEs are simulated via a single `lte-uesoftmodem` instance. Today the CI tests just with one UE and architecture has to be reviewed to allow a number of UE above about 16. This work is on-going.
As for the rf simulator, no specific hardware is required. The [L2 nfapi simlator page](L2NFAPI.md) contains the detailed documentation.
