Internet of Things (IoT) designs mesh together several design domains in order to successfully develop a product. Individually, these design domains are challenging. Bringing them all together to create an IoT product can place extreme pressure on design teams. The Tanner custom IC design flow is architected to seamlessly work in any of these design domains by employing an integrated design flow for design, simulation, layout and verification. Using a racing team tire pressure system, this paper walks you through this design flow, pointing out the unique solutions to IoT design.
