The IntelliProp IPP-NV186A-BR is an NVMe-to-SATA Bridge that utilizes the IntelliProp NVMe Target IP Core and the IntelliProp SATA AHCI Host Core to create an NVMe-to-SATA protocol bridge. The bridge is architected such that the command submissions, completion notifications and data transmissions may be either passed through without interruption or intercepted for analysis or modification. The architecture implements a ”sandbox” area in the bridge so that IntelliProp customers may implement custom RTL and/or firmware in the bridge.
The NVMe protocol interface is compliant to the NVMe 1.4 specification and the SATA interface is compliant with the SATA 3.3 specification as defined by the Serial ATA International Organization (SATA-IO) and supports version 1.3.1 of the SATA AHCI specification. The IPP-NV186-BR is fully verified using a coverage driven methodology in pseudo random simulation.

Functional Description
The IntelliProp NVMe-to-SATA Bridge, IPP-NV186A-BR, implements a protocol bridge by receiving and parsing commands via the IntelliProp NVMe Target Core and forwarding them to the IntelliProp SATA AHCI Core for delivery to the SATA SSD. The protocol bridging is done with a Processor. Customers may modify or add additional code to the bridging software. A processor is expected to receive and properly complete administrative and I/O commands from the NVMe Target Core. As a result, the NVMe-to-SATA Bridge provides transparency between the NVMe Host and the SATA SSD, while offering the designer flexibility in command and data manipulation.
