Setting Resistance and Inductance (RL) Analysis Parameters in 2D Extractor

To set up a Resistance and Inductance (RL) analysis, first add a solution setup.

Then, from the Solve Setup window:

1. Select the RL Advanced tab.

   The RL Advanced options display.

   

2. In the Convergence area, specify the following:
   • Minimum Number of Passes – the minimum number of mesh refinement cycles. 2D Extractor will not stop analysis until after this number of passes has been completed.
   • Minimum Converged Passes – the minimum number of passes that must meet convergence criteria before the adaptive analysis will stop.
   • Percent Refinement Per Pass – determines how many tetrahedra are added at each iteration of the adaptive refinement process. The tetrahedra with the highest error are refined. The default value is 30%.
   • Use Loss Convergence – select to use loss in the convergence criteria.
   • Use Parameter Convergence – select to use RL matrices in calculating convergence. Parameter convergence is determined based on the values of previous pass matrix and the current matrix. The maximum delta of a matrix entry is calculated by comparing entries of previous matrix and current matrix. The final delta is given by: Final delta (%) = 100 X (maxdelta / max value).

     If the final delta is less than the target delta, then the pass is considered converged with respect to parameter convergence.

     Select L Only for a lossless matrix, or RL for a lossy matrix.

     • Percent Error – the desired solution accuracy. Smaller values produce more accurate but slower solutions; larger values produce less accurate but faster solutions.

3. Click OK.
