Advantages of using asynchronous reset
Implementation of asynchronous reset requires less number of gates compared to
synchronous reset design.
Asynchronous reset is fast.
Clocking scheme is not necessary for an asynchronous design. Hence design
consumes less power. Asynchronous design style is also one of the latest design
options to achieve low power. Design community is scrathing their head over
asynchronous design possibilities.
Disadvantages of using asynchronous reset
Metastability problems are main concerns of asynchronous reset scheme (design).
Static timing analysis and DFT becomes difficult due to asynchronous reset.
