NVMe VALIDATION TEST SUITE

Overview

Non Volatile Memory Express (NVMe) is an interface controller specification built for accessing Solid State Drives(SSD) over a PCIe channel. NVMe has enabled greater data I/O and throughput performance of Flash based SSD storage units. NVMe has gained more traction in recent days due to their high performance benefits over its counterpart.

Atria Logic NVMe (AL_NVMe) post silicon test validation suite offers an environment for system level validation of NVMe Controller. The test suite defined is compliant and interoperable with standards defined by UNH_IOL. Additionally, it also provides other test features for greater confidence on the design and performance. It supports Linux based environment with ease of portability across systems.

Architecture

The validation environment is developed from off the shelf hardware and software components. The Atria NVMe Validation suite has Intel Galileo Development board and Xilinx Zynq ARM based FPGA SoC. The development boards can be interchangeably used as a host and Endpoint.
