Simultaneous Routing and Feedthrough Algorithm to Decongest Top Channel
Shashank Prasad, Anuj Kumar · 2009
In macrocell based SoC design, a routing plan to decongest top channel is an important step during floor planning. While previous approaches attempt at reducing congestion of chip as a whole, there is no attempt to specifically decongest top channel. We present an algorithmic approach to decongest top channel by using very few feedthroughs. Results show that compared to conventional methods, we can decongest top channel by using 20% lesser feedthrough buffers, and better top channel routing resource utilization.
