Overview & Features

Description

Developed in cooperation with Tokyo Electron Device (TED), GRL’s UHS-II Protocol Card Tester & Host Emulator (GRL-UHSII-EMU) is the only tool that tests conformance with SD Association UHS-II Protocol Test Guideline Version 1.0 at the click of a button. This combined Hardware and Software test platform provides a self-verification environment for UHS-II Card and Host, covering almost all items defined in the SDA UHS-II Protocol Test Specification as well as a highly configurable environment for stress testing and validation.

GRL-UHSII-EMU validates the reliability of UHS-II Cards/Hosts by allowing tests to be run in random or sequential order, or continuously to identify card performance over a period of time. The tool provides easy-to-understand Pass/Fail test results and protocol trace captures.

GRL-UHSII-EMU also provides powerful tools to discover true UHS-II Card design performance, including error insertion and programmable response time for Host-issued packets. To identify real card throughput at various data lengths, GRL-UHSII-EMU provides the ability to transfer data from 1MB to 1GB and calculate throughput in low power and fast mode.

GRL’s UHS-II Interposer Board (sold separately) is an ideal signal acquisition tool for use with GRL-UHSII-EMU.
