For those involved in debug and trace projects, one of the fundamental challenges is how to extract greater volumes of trace data from ever more complex devices, using ever-increasing higher-speed serial interfaces. This challenge is driven by the product of more—more data being transmitted inside devices, more functions happening at once on a die, and more components being integrated within devices. And the challenge is universal regardless of the application area—whether it's the Internet of Things (IoT), automotive, 5G or other areas.
The “MIPI Debug & Trace Connector Recommendations” white paper has been an invaluable resource for the global electronics developer community since its initial release in 2007. A new edition of the white paper (renamed from “MIPI Alliance Recommendations for Debug and Trace Connectors”) is now available to download from the MIPI Alliance website.
Whether you're just getting started with MIPI Debug solutions or you're interested in a more in-depth discussion of MIPI Debug for I3C℠, members of the Debug Working Group will cover it at upcoming webinars on 27 January and 17 February.
Next week, MIPI Debug Working Group Chair Enrico Carrieri and working group member Matthew Schnoor will take an in-depth look at the recently released MIPI Debug for I3CSM v1.0, which allows system designers to dynamically debug and test application processors, power management integrated circuits, modems and other power-managed components.
The smaller and more power-constrained systems being developed today for the Internet of Things (IoT), mobile devices, automotive and other use cases demonstrate the value of low-bandwidth interfaces for debug and trace. At the same time, the flexibility and scalability that these new use cases require have revealed crucial shortcomings in legacy low-bandwidth interfaces that are structured statically, such as JTAG/cJTAG, I2C and UART.
Earlier this year, the full lineup of MIPI debug and trace specifications was made available to the broader community, giving developers not only a standard, layered set of interfaces and protocols, but also an alternative to using expensive proprietary testing tools.
In recent articles in Electronics Media and Embedded Computing Design, Enrico Carrieri, chair of the MIPI Debug Working Group, shares how MIPI Alliance’s broad portfolio of debug and trace specifications can be used to streamline development for mobile, Internet of Things (IoT), 5G, automotive and many other applications.
