N2 - Basing on the distributed circuit theory, a simple and convenient method for power distribution planes (PDP) impedance calculation has been proposed, which can be utilized for power impedance analysis and capacitor decoupling design of PCB. Firstly, the power distribution plane is meshed non-uniformly and then the circuit netlist is automatically generated using MATLAB script. Secondly, the SPICE models of meshed cells, decoupling capacitors and connection vias are built separately and finally, the power port impedance located on the PDP is obtained by AC circuit simulation under the universal SPICE simulation environment. At the end of the paper, an example is given to demonstrate the proposed method. The simulation results are compared with those of commercial software and they agree well with each other.
