PROJECT DESCRIPTION : The Optimus HIM is a USB protocol host interface sub-system, used to interface UFM based SSD controller in the back-end. The UASP & BOT Protocol interfaces supported in USB sub-system.

ROLE : Verification

  • Testplan development for HIM-SS
  • Testcase development
  • Functional coverage definition and development
  • Debug of failures


  • Understanding USB2.0/3.0/3.1/3.2 protocols from scratch and develop test plan for whole sub-system in a short time.
  • Understanding control and data path in sub-system for E2E scenario development, debugs and to address queries if any from other audience or team members.


  • Good theoretical and working knowledge on USB2.0(FS/HS), USB3.2(Gen1x1, Gen1x2, Gen2x1 and Gen2x2).
  • Testplan development for HIM-SS.
  • E2E test cases development.
  • Defining and developing functional coverage for USB device.
