When considering timing, it is crucial to reduce the interconnection delay of the critical sink and decrease timing delay violations. In this work, we propose a detailed router that can consider the timing issue in the initial routing to find a good routing topology to reduce the interconnection delay of critical sink and optimize the delay for the worst three percent of delay of all nets in the re-routing stage. Experimental results show that our algorithm can effectively reduce the interconnection delay of the critical sink.
