White Paper: Improving Accuracy and Delivery Time in PCB Simulations

Today, time-to-market and component shortages are putting a lot of pressure on simulation engineers to deliver results quickly and accurately. These two requirements are contradictory. This is because, as a rule of thumb, simulation time increases in tandem with the accuracy of results. With signal integrity simulators based on 2.5D and 3D technology, it is paramount for engineers to find an optimum point of balance between simulation time and results accuracy.

This white paper outlines the results of a study examining the expected accuracy limitations for 2.5D simulator setups versus a more time-consuming 3D simulation outcome used as a golden sample. The study provides guidance on error levels, oversimplifications, and diminished result accuracy with 2.5D simulators. Engineers can use these guidelines to pursue simulation setups that suit their own unique accuracy and timeframe requirements.
