1.2.2.1.9. Plane Section

In the Plane table, you can set the tool to Calculate, Custom, or Ignore. For a fully customized workflow in which each rail group can have different settings:
  1. Select the Plane_Cap tab in the PDN tool 2.0.
  2. Set the parameters to match your system, and notice that the Total planar capacitance and Total sheet resistance values are updated automatically.
  3. In the System_Decap tab, select the Custom option for each group where a custom plane is required.
  4. Enter the calculated Ctotal and Rtotal values into the Plane section of the System_Decap tab.

Setting the Plane table to Calculate or Ignore causes the System_Decap tab to use the same global settings for all rail groups.
