UFS20COMP UFS Test Suite now offers deep packet inspection with protocol aware rule checking and analysis of the UFS standard for mobile computing memory applications

Warning status flags

Protocol Insight today announced that they will be demonstrating the new conformance and debug analysis capabilities of their UFS Test Suite at the upcoming MIPI® Alliance meeting in Shanghai, China on October 9th, 2014.

Universal Flash Storage (UFS) memory is designed for embedded and removable flash-based storage in mobile devices and systems requiring high performance and low power consumption. The UFS standard was developed by JEDEC, and is based on the MIPI® M-PHY physical and Unipro® protocol layers. UFS offers a low active power level and a near-zero idle power level, which, combined with the power-saving attributes of the related MIPI specifications, allows for significant reductions in device power consumption.

Protocol Insight’s UFS20COMP UFS Test Suite, first announced in June at the MIPI Alliance meeting in Budapest, Hungary, is now much more than just a compliance test suite. In addition to verifying compliance with the JESD224 Conformance Test Specification, it offers new analysis capabilities while inspecting every packet for protocol conformance to JESD220B version 2.0.

New Conformance and Analysis Capabilities
Warning status flags spell out any test results that do not conform to a “shall” requirement specified in JESD220B UFS standard Version 2.0. For example, in this screenshot the UFS Inquiry DATA IN packet (Packet 0) has an EHS length value of 0xaa in the LUN 0, HSG1, X1 link configuration. Since JESD220B states in Table 10.3 that “the Total EHS Length value shall be set to zero” this packet does not conform to the standard and is flagged with a Warning status.

Test results can now be grouped, filtered and summarized to get a better picture of overall device performance. Analysis can be done by test parameters such as warning status, test category, individual tests, or test rules, or by packet characteristics such as packet number, byte, LUN, speed, and link.

For further analysis, individual packets can be viewed in a packet decode pane in a structure consistent with JESD220B.

Pricing and availability:
A beta release of the UFS20COMP UFS Test Suite is available now, and version 1.0 will be released in October 2014. Contact sales@protocolinsight.com for v1.0 release schedule and pricing information.
