Certifying Models

There’s not much new about using models to start the design of a complex system. From an algorithmic standpoint, Matlab forms the basis for high-level design, and Simulink allows for the next step of modeling such a system in a more concrete fashion.

When the model is ready for detailed implementation, code can be generated for use downstream.

But, if you’re working on a piece of equipment intended for a safety-critical application, or, for whatever reason, some other usage subject to one of the many software standards, how do you know that the generated software will pass muster? How can you document that you did the requisite testing before moving forward?

LDRA and Simulink have moved to address this question by integrating LDRA’s software certification tools into Simulink. This allows for instrumentation of the code for analysis by LDRA’s certification engine. There are a variety of standards that can be selected as well as a number of different code coverage models.

This approach anticipates greater attention to model-driven design in standards updates such as DO-178C.

Understanding the Foundations of Quiescent Current in Linear Power Systems

Sponsored by Texas Instruments

Minimizing power consumption is an important design consideration, especially in battery-powered systems that utilize linear regulators or low-dropout regulators (LDOs). Read this new whitepaper to learn the fundamentals of IQ in linear-power systems, how to predict behavior in dropout conditions, and maintain minimal disturbance during the load transient response.

General Port Protection

Sponsored by Mouser Electronics and Littelfuse

In today’s complex designs, port protection can be a challenge. High-speed data, low-speed data, and power ports need protection from ESD, power faults, and more. In this episode of Chalk Talk, Amelia Dalton chats with Todd Phillips from Littelfuse about port protection for your next system design.
