All Implemented Interfaces:

ComputeNodesI<RawComputeCodeStore>

public class RawChip
extends RawProcElements
implements ComputeNodesI<RawComputeCodeStore>

This class represents the raw chip to which we are compiling. This class tries to deal with the collection of RAW tiles. See RawProcElements for dealing with I/O devices, and dealing with geometry that could include I/O devices as well as tiles.
