1.2.2.1.13. Decoupling Section

You can set Decoupling to Manual or Auto. If you select the Auto option, any change you make to the system is automatically reflected in the decoupling solution. You can also view the impedance chart per rail group or VRM.

Selecting the Manual option allows you to:

  • Lock in calculated decoupling solutions from being further optimized by any changes made to the System_Decap tab.
  • Add or remove the number and type of decoupling capacitors in the Results Summary section. You can see its immediate impact on the impedance profile curve.
