-- Notes on Implementations
-- Generates ILA, ICON, and VIO cores using Xilinx ChipScope with
-- following options:
-- ICON => generates to control two devices (e.g. two control port)
-- ILA  => generates to capture two output signal (e.g. two trigger)
-- VIO  => generates one async control output to control reset signal on design
