A cluster is a group of logic elements. The type of elements that make up the cluster is determined by the device type.
A super cluster is at least two clusters (SX). Modules in a cluster can be connected by fast or direct connects.
Use these areas as guides to ensure that the nets are fast/direct connect for implementation. Nets that connect within a rectangle can be implemented as fast or direct connects, depending on availability. For details about fast connects and direct connects, please see the FPGA datasheet for your device on the Actel web site.
Note: This feature is only available for the Axcelerator, eX, SX-A, and SX families.
To view clusters or super clusters, from the View menu, choose Static Objects, and then choose Cluster or Super Cluster. The cluster areas appear in the ChipView window.
