1.4 Routing Architecture

(Ask a Question)

The PolarFire family supports two types of routings—intra-cluster routing and inter-cluster routing. The intra-cluster routing connects the LEs within a cluster, and inter-cluster routing connects LEs between multiple clusters. The intra-cluster routing has lower propagation delay compared to inter-cluster routing. When connecting the adjacent clusters, inter-cluster routing also has additional short routing connections for faster routing.
