Mentoring to manage variables in automotive avionics design

Mentor Graphics, a leading manufacturer of electronic design automation technology, recently released a research report on how to use modern wiring design tools to meet the challenges of complexity. Option codes and expressions can simulate variables in automotive projects, and full-featured toolkits can obtain best practices and rules that are adopted in the form of constraints. Automation can help designers manage complexity in a stable, coherent, and low-cost manner.

Report author Simon Holdsworth has more than 20 years of experience in the electronics design automation industry and has been working in the field of wiring harness distribution since 1998. Before entering Mentor, he worked at Innoveda, and before that at Transcendent, where he was responsible for developing and deploying a new generation of electrical design tools for a large automotive manufacturer. During this period, Simon mainly held technical positions in the development, marketing and consulting sectors. Now he is a technical expert specializing in wire synthesis and automation. Simon began his career as an electronic engineer. He holds a master's degree in engineering from Cambridge University.

Simon Holdsworth said: "The use of rules and constraints to guide a series of" change and impact "calculations, this concept is the logical conclusion of this article. Today's powerful computer electrical system design automation tools make the creation of virtual environments a reality In the virtual environment, each wire harness component, wire coil, and connection can be defined and tested long before the first hardware prototype is assembled. And in this environment, it is easy to analyze the impact of various changes and at the same time be able to determine the performance And the profit angle to optimize the harness. "

Metrics can help designers answer these and other questions

The field of vehicle electrical system design is repeating the history of integrated circuit and printed circuit board (PCB) design years ago. The technical complexity of these areas began to exceed the scope of design engineers can independently understand. There are too many variables to consider, and too many rules to enforce. Today, automotive designers need to respond to various options, different configurations, model upgrades and modifications designed to meet the requirements of consumers and regulators. Whether it is a two-seater sports car or a large jet aircraft, the increasing complexity of electrical systems is often regarded as the number one challenge facing transportation designers today.

For past integrated circuit and printed circuit board designers, they can turn to electronic design automation software. Today's automotive designers can use powerful new computer tools. Compared with previous electronic design automation software, computer tools provide some of the same structural design and can bring the same advantages of speed, efficiency and accuracy.
