NVMe VIP: Verification Features

I ended my last blog post with a more-or-less complete NVMe VIP test-case example, trying to show everything from basic setup to doing an NVM Write followed by a Read. We are going to change gears a bit here, moving from the NVMe commands to some of the VIP features that are available to assist in your testing.

NVMe VIP Architecture: Host Features

In my last post, I covered a basic NVMe VIP test-case including some basic setup, sending a command and receiving a completion. Here, we’ll look at a few more NVMe commands, touching on some of the features and capabilities of the VIP.

Synopsys NVMe VIP Architecture: The Host Protocol Layers

Our previous post on NVMe was an overview of the NVMe protocol. We will now start looking closer at the VIP-proper, looking initially at the NVMe Host Protocol layers. This will provide an introductory overview of sending commands to the NVMe Controller.

The Synopsys NVMe VIP: A High Level View

Overview 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.
