-- 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
