##Supported Options
##-----------------
##GUI=1        Launch the build in the Vivado GUI.
##CHECK=1      Launch the syntax checker instead of building a bitfile.
##SYNTH=1      Launch the build but stop after synthesis.
##TOP=<module> Specify a top module for syntax checking. (Optional. Default is the bitfile top)
