  • Adaptive mesh resolution in electric circuit simulation and analysis
    Patent number: 8448117
    Abstract: An adaptive mesh of virtual nodes is provided to analyze the performance of a power/ground plane pair having an irregular shape. Plane transmission line characteristics and regional modal resonances can be modeled accurately, and with a significant decrease in simulation time as compared to traditional methods. A variable-sized cell structure is constructed with smaller cells in irregular regions and with larger cells in uniform regions. Grid nodes may thus stay aligned along length and width to allow parameters of equivalent circuit models to be scaled appropriate to the cell size.
    Type: Grant

    Date of Patent: May 21, 2013
