Abstract

This paper addresses a delay-driven layer assignment problem with consideration of via delay and coupling effect in the global routing stage. A negotiation-based framework is proposed to balance delay, congestion, and via count. Coupling capacitance is considered using a probabilistic look-up table. Finally, the proposed algorithm uses both parallel wires and wide wires to reduce wire delay. The effectiveness of our layer assignment algorithm is supported by extensive experimental results.
