Routing Resources
Clusters and SuperClusters can be connected through the use of two innovative local routing resources called
FastConnect and DirectConnect, which enable extremely fast and predictable interconnection of modules within
clusters and SuperClusters (Figure 1-5 and Figure 1-6). This routing architecture also dramatically reduces the number
of antifuses required to complete a circuit, ensuring the highest possible performance.
DirectConnect
• No antifuses
• 0.1 ns routing delay
FastConnect
• One antifuse
• 0.4 ns routing delay
Routing Segments
• Typically 2 antifuses
• Max. 5 antifuses

DirectConnect
• No antifuses
