Crash Course: Frequency Sweep Analysis Using SIwave and AEDT Circuit

Step-by-Step Guide

1. Upload Your PCB:
   • Start by uploading your PCB.
   • Click on the icon to view the five types that SIwave supports, especially IPC 2581 and ODB++.
2. SIwave Wizard:
   • Click on the SIwave Wizard icon and navigate to the DCIR drop analysis.
   • Select the power plane or RF line you wish to analyze. You can select more than one.
3. Add Sources:
   • Select to add a voltage source, a current source, or both.
   • Example: Place a voltage source at the VRM and a current source at the CPU.
   • You can adjust the values as needed. These values will be used for all frequencies.
4. Configuration and Validation:
   • Configure and validate your setup to ensure everything is correct.
   • Once validated, click "OK" and close the dialog box.
5. Activate Power Plane:
   • Activate your power plane and highlight the 1.2-volt line.
   • Add voltage probes as needed. For example, place Voltage Probe 1 and another probe as required.
6. Simulation and Frequency Sweep:
   • Navigate to the simulation section and select "Compute Frequency Sweep."
   • Choose your frequency band and the number of frequencies to analyze.
   • Select to display the field between VCC and the ground layers, then launch the simulation.
7. Results and Visualization:
   • Once the simulation is complete, click to view the solution.
   • Plot the probe voltages you assigned, such as the magnitude.
   • The Electronic Desktop will open, allowing you to see the results.
   • You can also plot the field and animate the frequencies.
