High Bandwidth Memory (HBM) is available in AMD Versal™ HBM Series devices. HBM supports data rates up to 3200 Mb/s. HBM is accessed through either a NoC connection or through a direct PHY connection. The PL can bypass the PHY to implement soft memory controllers or to support a chip-to-chip interface. The bypass mode has approximately half of the bandwidth of the NoC mode. HBM is configured using the AXI NoC IP wizard in the design flow.
