MIPI A-PHY Compliance Program Test Event
Test equipment vendors and companies that have devices under test (DUTs) will participate in a 14-18 July 2025 A‑PHY Compliance Program test event at the Resillion testing labs facility in Hasselt, Belgium. The event will focus on exploratory Rx test, Tx, correlation and onboarding of additional test equipment vendors.
Participation will not result in certified compliance, but device vendors will receive valuable feedback about their devices and have the opportunity to collaborate with others in a confidential environment protected by non-disclosure agreements. Data will be collected to allow correlation of the results, potential debugging and feedback on the specification and CTS. However, results will be displayed anonymously. All testing will be performed in a large space suitable to accommodate multiple test stations.
About the program
Initiated by the A-PHY Working Group, the compliance program is being established to help ensure that MIPI A-PHY® and A-PHY-related specifications in MIPI's Automotive SerDes Solutions (MASS™) framework meet the industry’s needs and requirements. The program is focused on testing A-PHY first, using the recently published A-PHY Reference Compliance Test Suite. Later phases will extend to the many A-PHY protocol adaptation layer (PAL™) specifications, which enable higher-layer protocols to operate seamlessly over the MIPI A-PHY physical link.
A second event in 2025 is currently being planned for December. The testing focus areas and location are still being finalized.
For more information about participating in these events, please contact the A-PHY Compliance Program team.
Participation Requirements
The Call for Participation for the July event is now closed. If you are interested in participating in a testing event or have questions about the program, please contact the A-PHY Compliance Program team.
