Cadence Design Systems

In this paper, we compared the PDN models obtained with 2.5D extractor and 3D full wave solver. The resulted deviations on both frequency domain impedance curves and time domain power noise brought by these two kinds of models were analyzed. The influences of different 2.5D extractor setting including pin based vs net based, selections of reference nodes, s-parameter vs spice model, are investigated. Similarly, the influences of key 3D solver setup options were also studied and the corresponding effects were summarized. In the end, a set of design guideline on selecting the best approach for different design scenarios are presented.
