Device congestion can potentially lead to difficult timing closure if the critical paths are placed inside or next to a congested area or if the device utilization is high and the placed design is hardly routable. In many cases, congestion will significantly increase the router runtime. If a path shows routed delays that are longer than expected, analyze the congestion of the design and identify the best congestion alleviation technique.
