# Filename    : dds_compiler_1.sh
# Simulator   : Xilinx Vivado Simulator
# Description : Simulation script for compiling, elaborating and verifying the project source files.
#               The script will automatically create the design libraries sub-directories in the run
#               directory, add the library logical mappings in the simulator setup file, create default
#               'do/prj' file, execute compilation, elaboration and simulation steps.
