1.2.2.1.10. Spreading Section

In the Spreading table, you can set the tool to one of the following options:
  • Ignore
  • Low
  • Medium
  • High
  • Custom
For a fully customized workflow in which each rail group can have different settings:
  1. Select the Library tab in the PDN tool 2.0.
  2. Set the parameters in the Spreading R and L table to match your system.
  3. Examine the range of spreading R and L values to determine if you need a custom R and L. If a custom R and L is warranted, select Custom in the System_Decap tab and set the R and L values directly.

Setting the Spreading table to Low, Medium, High, or Ignore causes the System_Decap tab to use the same global settings for all rail groups.
