# Source files for the max_hold component are added to the project. The Project
# 'add_file' method accepts a file path and library name, if no library is
# specified it will default to 'work'. Other file attributes are available but
# not covered in this example.

# When adding the testbench file we supply a 'synthesise' attribute and set it
# to 'False', this tells the synthesis tool not to try to synthesise this file.
