NVM Express or the Non-Volatile Memory Host Controller Interface (its prior name was NVMHCI, now shortened to NVMe) is a host-based software interface designed to communicate with Solid State storage devices across a PCIe fabric. The current Synopsys NVMe Verification IP (VIP) is a comprehensive testing vehicle which consists of two main subsystems – the first is the SVC (System Verification Component), the second is SVT (System Verification Technology). The SVC layers are associated with the actual NVMe (and PCIe, etc.) protocol layers. The SVT provides a verification methodology interface to UVM and other methodologies such as VMM and OVM.

Although the VIP supports multiple versions of VIP, we will initially be version agnostic, speaking more in generalities of the protocol in order to provide a 10,000’ view of the protocol and its support in the VIP. Future discussions will delve deeper into particular details of NVMe and features of the Verification IP.
