3. e workflow from the RF design tools and the PCB design tools, so that IP cre- ated in either can be shared for either integrating RF PCB IP into the larger missed-signal system or for importing the PCB IP into the RF design platform for design verification with EM/circuit co-simulation. Is there a role for AI in RF design? Yes, generative AI holds immense promise in addressing numerous RF system design chal- lenges. AI will have many uses in RF, and Cadence is focused on several areas where we believe AI can help engineers accelerate prod- uct development, make product and instruc- tional information more accessible, and drive our soware to perform more complex tasks through query. By leveraging machine learning algorithms, generative AI can automate the design process, enabling rapid prototyping and exploration of the design space. It can optimize designs, improve PPA, and reduce time to market. Fur- thermore, generative AI can foster innovation, enabling designers to create novel and custom- ized solutions that meet diverse needs. Gen- erative AI for chip, system, and product design is a combination of large lan- guage models to bridge human language communication and technical design, reinforcement learning to automate decision-making for optimizing and operating on designs, and transfer learn- ing to apply past solutions to new projects. Another vision for the future of AI in RF is how the technology could help the newly grad- uated engineer be more efficient by exploring and refining design decisions much more rap- idly, basically giving them access to know-how that usually is reserved for the engineer with five to 10 years of experience under their belt. What are the most important things for PCB designers and design engineers to remember when working in the RF arena? When it comes to RF, especially at higher fre- quencies such as millimeter-waves, physical design matters. If you move metal around, ver- ify the impact with EM analysis and spend time ensuring the simulation is properly defined and the results make sense. Collaborate across teams so work and effort isn't wasted. If you're new to RF design, watch a tutorial on how the Smith chart works and gain a basic under- standing of impedance matching. Seek out RF knowledge from the experts who have built hardware and spend as much time as possible in the lab with hardware and in front of the computer running simulations to reinforce your understanding of how transmission lines transform impedances.
