*******************************
FCN Kernel Test
*******************************

L2 FCN kernels have been tested against the implementation in C++ on host side.

Test FCN kernels
==============================
There are two pre-build L2 FCN kernels, one with 1 FCN CU (Compute Unit) and the other one with 4 FCN CUs. 
Both of the two kernels can be tested individually. 
To launch the testing process, please navigate to each testcase directory under **L2/tests/hw/mlp/**. 

.. code-block:: bash

  make run TARGET=sw_emu/hw_emu

The above command will test and verify the FCN kernel via Vitis software-emulation or hardware-emulation.
Once the emulations are pased, one can use the following command to build FPGA bitstream 
and launch the kernel on Alveo U250/U50 FPGA card. 

.. code-block:: bash

  make build TARGET=hw
  make run TARGET=hw
