Avoid costly chip respins and system integration delays with best practices customized to your company. Implementing these best practices will save your company time and money and increase the quality of your products. In this workshop, we present approximately 300 best practices of hardware/firmware interface design and explore the fundamental principles underlying them. We teach engineers how to customize and adapt these best practices for your specific development processes. Your engineers will emerge from the workshop with a set of best practices tailored to your environment.
