Module Organization
C-cell and R-cell logic modules are arranged into horizontal banks called Clusters, each of which contains two C-cells
and one R-cell in a C-R-C configuration.
Clusters are further organized into modules called SuperClusters for improved design efficiency and device
performance, as shown in Figure 1-3. Each SuperCluster is a two-wide grouping of Clusters.
