UFS Test Solutions

Protocol and performance validation of UFS 2.1/3.1/4.1 device is complex since it is an embedded intertace and operates with ditterent vendor SoCs. A UFS device must operate seamlessly with multiple SoC vendors and hondle unexpected protocol packets without causing system-level failures.

Common validation workflows include:

• Test the device with multiple SoC platforms
• Test the device for UniPRO Conformance Test Suite (CTS) and UFS CTS to ensure interoperobility.

How Prodigy Supports:

• Prodigy Technovations provides different interposers which can be interfaced to SoC plattorms tor easy access to test points tor oscilloscope and Protocol Analyzer
• PGY-UFS4-PA UFS Tester delivers complete UniPRO CTS and UFS CTS capability for comprehensive device validation. Also, scripting to write custom test cases with error injection capability.

SoC and device IC development goes through multiple stages before being tape-out of the IC. Due to design complexity and the need for first-time success, semiconductor vendors increasingly rely on extensive pre-silicon validation using FPGA-based prototype or emulator boards.

Common Workflow

• Interface the UFS device to FPGA Platform where SoC or UFS IP with MPHY test chip is present and run different test cases
• Interface the real-world SoC with UFS host support

How Prodigy Supports:

• Prodigy Technovations offers a UFS Tester Board that interfaces with FPGA prototypes or emulator board. It converts FPGA PHY outputs to MPHY-compatible signaling for UFS devices.
• Prodigy also provides FPGA IP that enables users to generate low speed Phy adapter layer and UniPRO packets in PWM mode. The tester board includes MiniSMP connectors for direct connection to UFS 3.1 / 4.0 protocol analyzers.
• Prodigy Technovations provides an interposer to interface real-world UFS SoC platform to a FPGA prototyping board or emulator.

UFS storage devices are widely used in mobile phones. Probing MPHY/UFS signals is extremely challenging since there are no test points to access these signals. UFS storage devices store bootloader and user data. Mobile phone OEMs must ensure flawless operation of the UFS interface at different use cases.

Prodigy Technovations offers board-to-board (B2B) interposers along with the PGY-UFS3.1/UFS4.1 Protocol Analyzer, making it practical to validate real mobile phones and perform detailed protocol analysis over PACP, UniPRO and UFS Protocol layer.

New generation laptops and tablets increasingly use UFS storage devices for boot and storage purposes. Typically, UFS storage devices are mounted on the bottom side of the PCB, making the access to test point is difficult for debug and validation.

Prodigy Technovations provides B2B interposers compatible with solder- down probes and miniSMP connectors for accessing MPHY/UFS signals. Also provides customized stand to raise the test platform. The test platform is raised using a customized stand, Engineers can conveniently connect PGY- UFS4-PA protocol analyzers or oscilloscopes for protocol and electrical validation to the Board-to-Board Interposer.

UFS device vendors can source different SoC platforms with UFS devices. Now users rework on the SoC platforms to place UFS interposes from Prodigy Technovations and run test cases from SoC to make sure SoC platform safety boots from UFS device as well all read write operation. PGY-UFS3.1 / 4.1-PA can monitor protocol traffic and report errors.

UFS firmware development is continuous development activity, driven by new feature requirements and field issues. It is essential to ensure the firmware is passes UniPRO and UFS conformance Test Suite (CTS) for every new firmware release.

Prodigy Technovations provides UFS 3.1/4.0 Exerciser (Tester)supports UniPRO 1.8/2.0 and UFS 4.1 CTS. Engineers can run conformance test suite tests to test new firmware to ensure conformance to CTS. Tester can run custom, performance, and reliability tests, ensuring firmware is production-ready.

UFS storage device manufacturers need to test the UFS devices for varying temperature ranges, sudden power shut down, Read/Write operations and Power Mode changes in the manufacturing line.

Prodigy Technovations multi-socket UFS tester enables long-duration reliability and consistency checks across multiple devices. The UFS 3.1/4.0 Exerciser supports custom and vendor-specific test cases, ensuring robustness before deployment.

Validating UFS devices across multiple host SoCs ensures they can handle unpredictable protocol sequences without system failures. Engineers often need multiple SoC platforms to run MIPI UniPro and UFS CTS test cases.

Testing Across Multiple SOCs:

Device vendors can rework SoC boards with Prodigy UFS interposers and run host-initiated test cases to verify safe boot, read/write performance, and protocol reliability. PGY-UFS3.1/4.1-PA monitors traffic and flags errors.

UFS storage devices are widely used in automotive infotainment and ADAS. In safety-critical environments, UFS protocol reliability, timing accuracy, and consistent behavior under varying conditions are essential. Due to compact ECU designs, probing UFS test points is difficult.

Prodigy Technovations board-to-board UFS interposers and solder-down probes enable easy access to test points for protocol analysis and electrical validation. UFS Tester can be used to validate different vendor UFS Storage devices for UniPRO and UFS CTS so that users can interchangeably use the UFS storage devices in the final product.
