Abstract
Methods and systems are described herein relate to automatic channel identification of high-bandwidth memory channels and subchannel generation. An HBM channel identification system may perform a sequence of operations to identify HBM channels within a netlist of an interposer: channel dimension prediction, channel bounding box prediction, channel orientation derivation, subchannel partition, and subchannel routing region creation. In one example, an HBM channel identification method includes identifying candidate nets within a netlist. A bounding box that includes one or more nets of the candidate nets is determined. Once the bounding box is determined, the orientation of the box is determined and used to determine a pattern of bumps within the bounding box. Finally, a subchannel is generated based on the pattern of bumps.
