#  Makefile for iterative compilation for AMD / Xilinx Vivado

#------------------------------------------------------------------------------
#
#
# INFO ------------------------------------------------------------------------
# - This is a top-level Makefile
# - It makes a bunch of Vivado project copies which differ only one variable
# - Then it compiles all projects in parallel and collects FMAX data
#
# - Please define var sweep range below
# - Separate vivado project will be created and compiled for every var value
#
# - This makefile is "make -j"-friendly
#
