Total Phase walks through the Promira Serial Platform, a single hardware box that can be configured for passive protocol analysis or active control of a target board, aimed at engineers working on I2C, SPI and related serial links. The core idea is to give “intelligent visibility” into what bytes actually moved on the bus while you are developing drivers, firmware, or board bring-up, without juggling a pile of separate tools. https://www.totalphase.com/

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

In analysis mode, Promira acts like a high-fidelity bus sniffer: it taps the lines, timestamps traffic, decodes protocol frames, and streams transactions live to the host UI. That real-time decode matters because you can keep the system running, interact with the device, and immediately correlate a wrong LED state (or any misbehavior) with the exact address, register, and payload that caused it, quickly.
In active mode, the same platform can also talk on the bus: it can generate transactions, emulate a controller, and deliberately manipulate devices to reproduce bugs or validate edge cases. The demo shows closed-loop work where a controller changes LED values while a second Promira instance monitors the bus simultaneously, giving you a tight feedback loop for debugging and test, cleanly.
They also position Promira as an upgrade path that consolidates capabilities previously split across dedicated adapters and analyzers, with features unlocked via software licensing as needs grow. Alongside Promira, the lineup spans USB and CAN interfaces for protocol bring-up, regression verification, and lab automation, and they hint at future ML-assisted anomaly detection and decode aids, though nothing is committed yet.
A separate part of the booth highlights Total Phase’s Advanced Cable Tester for production environments, using interchangeable modules to validate cable continuity, resistance, and signal-integrity targets for common connectors such as USB-C and HDMI. The emphasis is repeatable factory QA across batches rather than certification, with measurements that help catch marginal assemblies before they become field issues, at Embedded World North America 2025.
