Protocol Insight Announces the release of version 1.0 of their Universal Flash Storage (UFS) MIPI® Test Executive

UFS20COMP Test Executive provides deep packet inspection, protocol aware rule checking, and complete test coverage of the UFS standard for mobile computing memory devices

Colorado Springs, Colorado, November 10, 2014 – Protocol Insight today announced that version 1.0 of their UFS20COMP UFS Test Executive is now publicly available; previously it was only offered as an early beta to select customers.

Protocol Insight’s UFS20COMP Test Executive, first announced in June at the MIPI Alliance meeting in Budapest, Hungary, provides complete analysis of the packet protocol characteristics of Universal Flash Storage (UFS) devices, to debug and verify interoperability with compliant devices.

Test Configurations

The Test Executive analyzes the entire UFS response packet for conformance to the JESD220B UFS 2.0 and UniPro 1.6 specs. For example, the Test Executive evaluates over 30 of the major protocol characteristics of the Inquiry response packet, including the Basic UPIU Header, Data In and Response UPIUs, when performing Inquiry Test Case 7.1.1, even though only 4 checks are required to pass the JESD224 CTS.

UFS20COMP also performs compliance testing to the JEDEC JESD224 UFS Protocol CTS, for UFS v2.0 and UniPro v1.6.

17 test categories are currently supported:

o Inquiry
o Request Sense
o Mode Sense
o Mode Select
o Start Stop
o Format Unit
o Test Unit Ready
o Verify
o Send Diagnostic
o Report LUNs
o Synchronize Cache
o Pre Fetch 10
o UFS Task Management
o UFS Descriptor
o UFS Flag
o UFS Attribute
o UFS UPIU

Over 100 individual tests are included, for all permutations of LUN, Speed and Link Width supported by Keysight’s U4431A MIPI analyzer.

Additional test categories and tests will be added in subsequent releases for a total of over 200 tests in 30 test categories.

Pricing and availability:

UFS20COMP Test Executive v1.0 is available now. It is offered as a 12 month license with an annual renewal option, and operates in conjunction with the Keysight Technologies U4431A MIPI M-PHY protocol analyzer. Contact sales@protocolinsight.com for pricing information.

Protocol Insight Announces Protocol Conformance and Debug Analysis Tools for MIPI® Universal Flash Storage (UFS)

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

Colorado Springs, Colorado, October 3, 2014 – 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 9^th, 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.
