Patent 10551431 was granted and assigned to Cadence Design Systems on February, 2020 by the United States Patent and Trademark Office.
Described is an improved approach to implement EM analysis, where the analysis can be performed early stages of the design process. Tree-routing is implemented using a structural routing solution, where an automatic routing mechanism is performed to generate a complete routing tree. That routing tree is then used to perform topology-driven EM analysis at various stages of the design process.
