Trapped-ion quantum processors based on surface electrode Paul traps with integrated microwave conductors for near-field quantum control are a promising approach for scalable quantum computers. Due to increasing complexity of the processor chip models numerical analysis of the cause-effect relationship becomes challenging. In a complex multi-zone processor chip architecture, it is known that the electrode routing affects the ion transport, trapping and state control. To overcome these challenges already in the first design step, an automated electrode routing routine is proposed. Applying an iterative Method of Moments simulation process, cross-talk can be avoided while keeping the computational costs feasible. Challenges and benefits compared to straight forward approaches are discussed.
