Abstract :
In this paper, we present an efficient design flow for GALS systems based on the state-of-art commercial tools, we first designed an asynchronous wrapper equipped with handshake circuits and stoppable clock generator, and then selected a digital FIR filter as a design example. The simulation and verification show our proposed interface circuits is of good performance in terms of speed and area. The design efficiency is also improved by allowing standard tools to better support GALS based designs.
